Refractive Surgery Services

What is refractive error? The function of the eye is to see clearly the objects around us. The inability of the eye to accurately focus the rays of light coming from distance on the retina is called refractive error. This condition may be either because the eye is too short or long in length, or because the cornea or lens does not have the required refractive power. There are three types of refractive errors: Myopia (near-sight): this is the condition in which the eye is too long and the light is focused in front of the retina. Distant objects are blurred but the near objects are seen clearly. The eye has too much optical power and to correct it the optical power is reduced by either minus glasses or contact lenses, or by surgery. Hypermetropia (long-sight): this is the condition in which the eye is too short and the light is focused behind the retina. The eye has less optical power than is needed. When young the eye can use the lens within the eye to compensate, but reading glasses are needed at a relatively early age. Later, distance glasses (plus) are needed as well, such that glasses for distance and near are required. Astigmatism: this is the condition where the eye does not focus the light evenly, usually due to the cornea of the eye being more curved in one direction than the other. It may occur on its own or may be associated with myopia or hypermetropia. What is Presbyopia? Presbyopia is the normal aging process, where the lens progressively loses its capacity to increase its power for near vision (loss of accommodation). The distance vision may be normal, but the near vision becomes blurred with age greater than about 45 years. This is corrected by wearing reading glasses (plus) for the near work. This condition may occur in itself or may be present alongwith pre-existing myopia, hypermetropia or astigmatism. What are the ways of treating refractive errors? The refractive errors may be treated by either of the following ways:Glasses: this is the simplest and most popular way of correcting refractive errorsContact lens: this option is cosmetically much better though the maintenance and cleaning of contact lenses may be cumbersome. There is also a slight risk of infection to the cornea, if the contact lenses are not cleaned properly before use.Refractive surgeries: these are increasingly becoming popular with the advent of more predictable laser treatments. What are the various refractive surgeries? The refractive power of the eye can be changed by any of the three approaches:Changing the curvature of the cornea: this is the most popular mode of refractive surgery.Removing the natural lens and replacing it with an artificial lens of adequate power: it is similar to a routine phacoemulsification surgery, except that it is done in a clear lens and not a lens with cataract. As it is an invasive procedure and it also increases the chances of retinal detachment in eyes with high myopia, it is not recommended nowadays.Putting an additional artificial lens within the eye on top of the existing natural lens: this technique is still not very popular as it is also invasive and may increase the chances of cataract formation. What are the ways of changing the curvature of cornea? The commonly used methods for refractive surgery are:PhotoRefractive Keratotomy (PRK) : It is being used less commonly nowadays.Laser-Assisted In-Situ Keratomileusis (LASIK) :This is the most popular form of Laser treatment.LASEK (or Epi-LASIK) :This newer form of treatment may be suitable in some selected patients with very high power.

Laser Vision Correction Nandadeep Netralay does not advice laser vision correction (LASIK). Implantable Contact Lens (ICL) ICL corrects higher degree of refractive error which cannot be done by laser treatments. Implantable contact lenses (ICL spherical /Toric) is surgically implanted in the eye between the iris and the natural crystalline lens through a small corneal incision. Refractive lens exchange : In refractive lens exchange surgery the natural crystalline lens of the eye is replaced with an artificial Intra ocular lens (IOL) to achieve sharper focus, rarely it is opted for young people with very high powers. The surgical procedure is almost the same as cataract surgery and is done under local/topical anesthesia Instruments Available : Orbscan corneal topographer, Zywave Aberrometry, Specular microscope, Keratometer (auto/manual), Ultra sound Pachymeter

Such as nearsightedness (myopia), farsightedness (hyperopia),astigmatism or presbyopia, refractive surgery is a method for correcting or improving your vision. There are various surgical procedures for correcting or adjusting your eye s focusing ability by reshaping the cornea, or clear, round dome at the front of your eye. Other procedures involve implanting a lens inside your eye. The LASIK The most widely performed type of refractive surgery is LASIK (laser-assisted in situ keratomileusis), where a laser is used to reshape the cornea.Like other types of refractive surgery, the LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision.In most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes. The results improved vision without eyeglasses or contact lenses can usually be seen in as little as 24 hours.

Successful Refractive eye surgery can reduce or cure common vision disorders such as myopia, hyperopia and astigmatism.Refractive surgery requires an intensive pre-operative work-up and post-operative care to ensure the best possible surgical result.Refractive surgery offers tremendous benefits: clearer vision and freedom from dependence on glasses.

Popular Laser surgical method to address vision issues that include elimination of dependency on spectacles.

LASIK (Laser-Assisted In Situ Keratomileusis) is one of the surgeries that treat refractive errors of the eye. LASIK is a variant of excimer laser photorefractive keretectomy (PRK). Although LASIK is a newer procedure, it has become an increasingly common surgery which many people opt for to treat refractive errors.The primary difference between LASIK and PRK is that in the former, laser is used through an instrument called microkeretome to change the shape of the cornea. The microkeretome creates a thin flap of cornea, which is folded back, and the laser treatment is then performed under this flap. Visually recovery is usually faster as well, because the surface layer of the eye does not need to re-heal after being removed as it does in PRK.LASIK is an exciting surgical procedure that is capable of correcting a wide range of nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. LASIK is the acronym for laser assisted in-situ keratomileusis. The name refers to the use of a laser to reshape the cornea without invading the neighboring cell layers. LASIK is currently the most commonly performed refractive procedure in the United States and in India.LASIK was first performed in clinical trials in the U.S. in 1991. It was officially approved in 1996 in the U.S. It is important to note that the major components of the procedure have a long history. Ophthalmologists have been reshaping the cornea for over 50 years, creating a protective layer of tissue for over 35 years, and using the excimer laser since the 1980 s.LASIK combines the precision of the excimer laser that is used in PRK surgeries with the flap technique that characterizes ALK. Firstly, removal of the corneal surface tissue is not necessary and therefore, postoperative pain is substantially reduced compared to PRK. Secondly, postoperative visual acuity is restored within a few days rather than weeks. Finally, there is less corneal scarring in the long-term and greater stability of the correction.LASIK improves the uncorrected vision for distance one s visual capacity while not wearing corrective lenses in most patients who have the procedure. Nearly all patients can expect to achieve 20/40 vision, which most states consider good enough to drive without having to wear contacts or glasses, and many can expect to achieve 20/20 vision or better. However, there are no guarantees that you will have perfect vision. People who are most satisfied with the results of laser correction clearly understand the potential risks and complications and possess realistic expectations of what their vision will be like after surgery.The effects of LASIK are permanent. The effects of LASIK do not wear off. But, it is important to realize that a person s eye can still change internally. That is why many surgeons recommend having the procedure done after the major eye changes have occurred in one s life. For instance, LASIK is not recommended on children because their eyes change a great deal. They would need the vision fine-tuned in a few years. If the procedure is performed after the age of 18, the chance of long-term stable correction is more likely. Even the eyes of patients, over the age of 18, can still undergo further changes. Therefore, we recommend that you consult your surgeon so that he/she can review the changes you have had and help you make a decision whether or not you should wait. Patients should also note that while results are usually stable, they can be modified by enhancement procedures procedures performed after the initial one if necessary.

LASIK is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an exciter laser. The eye and vision errors The cornea is a part of the eye that helps focus light to create an image on the retina. It works in much the same way that the lens of a camera focuses light to create an image on film. The bending and focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is out-of-focus (blurred) or distorted. These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: Myopia: persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects.Hyperopia: persons with hyperopia, or farsightedness, have more difficulty seeing near objects as clearly as distant objects.Astigmatism: astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye.Combinations of myopia and astigmatism or hyperopia and astigmatism are common. Glasses or contact lenses are designed to compensate for the eye's imperfections. Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery. In LASIK surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power.

Removal of Glasses/ Contact lenses WHAT IS LASIK? LASIK EYE SURGERY HOW IT WORKS, RISKS, RECOVERY Lasik eye surgery is the most common elective procedure and is performed to correct nearsightedness, farsightedness and astigmatism.

ALL YOU EVER WANTED TO KNOW ABOUT LASIK !!Before you know what LASIK is, you need to understand essentially how the eye functions: Our eye works just like a camera, with the front glass of our eye called corneal bending the light rays inwards and the light getting fine focussed with the help of a lens on the camera film called retina. Finally the fibres from the film/retina make a wire/ optic nerve that takes all the signals from the camera(eye) to the computer( brain). If the eyeball is longer or shorter than normal or the shape of cornea is deviant from normal, a person needs to wear glasses or contact lenses to help focus the light on the eye camera film (retina) (image)

To treat nearsightedness/ hypermetropia, tissue is removed from the central zone of the cornea. This shifts the point of focus from in front of the retina to directly on the retina.

Patients wearing thick spectacles or high power contact lenses desirous of getting freedom from spectacles/contact lenses are offered latest refractive surgery options suitable for their eyes.They are first subjected to a dilated retinal examination to ensure that all is well in the back of their eyes prior to planning a laser vision correction procedure. If the patient has a retinal problem like retinal holes, it needs to be taken care of prior to planning LASIK surgery.Once through, the patient is then subjected to pachymetry( corneal thickness at various points on the cornea) and topography ( which shows the curvature of the anterior and posterior surface of the cornea at various points. This is done using the Pentacam from Oculus IncOnce the Doctor feels it is safe for the patients eyes to undergo refractive surgery, the patient is explained about the procedure in detail. Refractive surgery is performed using the WavelightAllegretto Wave laserby Alcon Inc.

A refractive error, or refraction error, is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity. An eye that has no refractive error when viewing distant objects is said to have emmetropia or be emmetropic meaning the eye is in a state in which it can focus parallel rays of light (light from distant objects) on the retina, without using any accommodation.

Kapil Eye Hospital provides surgery for removal of spectacles by Laser Lasik Equipment i.e. Zyoptix. For certain suitable patients ICL i.e. Implantable Contact Lenses are also implanted.

The ICL procedure is a type of refractive surgery performed by an ophthalmologists in which the ICL is surgically implanted inside the eye, where it resides permanently. The ICL requires no maintenance after the procedure and functions very similarly to contact lenses in improving visual acuity. For most patients, ICL provides permanent freedom from eyeglasses or contact lenses. Are You a Candidate for ICL IOLs ? Not all patients are candidates for ICL lens implantation, just like not all patients are candidates for LASIK. Some questions to help determine whether ICL IOLs are right for you include: Is your myopia within the range for which the ICL IOL has been approved (up to around -20.00 D)? Have you had a comprehensive eye exam to determine that your eye can safely accommodate an implantable lens? Of particular importance is the depth of the anterior chamber of your eye and the health of the corneal endothelium. Are you between the ages of 21 and 40? Even if you are outside this age range, you may still be a candidate for a ICL and should discuss with your eye surgeon. While a ICL does not treat blurry near vision due to presbyopia, a normal age-related condition that generally starts in your early 40s, monovision IOL surgery can help. Has your eyeglass or contact lens prescription changed in the past year? For vision correction surgeries, you must have had stable vision for at least a year. Are your eyes healthy? Conditions such as cataracts, glaucoma and untreated eye infections generally will prevent you from having a ICL. Are you in good health? Certain degenerative or autoimmune diseases such as Sjogren's syndrome, rheumatoid arthritis, type 1 diabetes, HIV and AIDS, as well as certain medications such as steroids and immunosuppressants may interfere with healing and final outcomes. ICL lenses are indicated for patients with high refractive errors when the usual laser options for surgical correction (LASIK and PRK) are contraindicated. Current ICL are designed to correct high myopia ranging from -5 to -20 D if the patient has enough anterior chamber depth (ACD) of at least 3mm. Implantable Contact Lens (ICL) Procedure ICL eye surgery is a relatively quick and pain free outpatient surgical procedure. Unlike LASIK surgery, no laser is required for ICL eye surgery and the procedure can be reversed by performing an additional surgery to remove the lens. What is LASIK? LASIK - Laser Assisted In-Situ Keratomileusis. How long is the treatment? The entire procedure takes around 15 minutes and is done as a day surgery procedure without the need for admission to hospital. Do I have to undergo any tests prior to Excimer laser treatment? Yes. Preoperative corneal and retinal evaluation would have to be carried out. They can be fixed by taking a prior appointment at the Doctor Eye Institute. Is it painful ? During the Laser treatment, there is no pain at all. However you may experience some mild ocular discomfort and watering during the first 24 hours after surgery. It will gradually resolve by second or third day. Painkillers and may be prescribed to ease the pain and discomfort.

LASIK is a surgical procedure for correcting near sightedness (myopia), far sightedness (hyperopia) and cylindrical (Astigmatic) refractive errors. LASIK stands for Laser-Assisted in Situ Keratomileusis. Procedure of LASIK During LASIK surgery, a flap is created in the outer layers of the cornea. The flap is hinged and lifted so the excimer laser can treat only the underlying layer of the cornea. This circular flap remains attached to the cornea by a small hinge of tissue. The hinge enables the flap to be lifted away from the central cornea. A laser can then be used to reshape the exposed mid-layer of the cornea.

a. Keratoplasty (Optical Therapeutic) b. C3R: It is anew and safe treatment modality for corneal ectasia. It is a technique which forms strong bonds between adjacent corneal collagen fibers using ultra violet light. The aim is to halt the progression of steeping of cornea (ectasia). It is most commonly done in cases of keratoconus. c. AMT (Amniotic Membrane Transplant) d. Pterygium Excision with Autograft with Glue

Custom Lasik offers a number of advantages over other forms of conventional lasik by reshaping the cornea with excimer laser based on a computer generated ablation map using data from the corneal topographer and wave front aberrometer system for each treated eye unlike going simply by your glass prescription which is prone for errors of judgment.To simplify, each eye is unique like your finger prints. Custom lasik is a revolutionary concept in lasik which customizes treatment for the correction of visual errors including the smallest of aberrations. In effect you could gain a theoretical visual acuity of 6/3 more like super vision.Custom lasik can treat a higher range of refractive errors with minimal risk, there by reducing or eliminating a life time dependence on glasses or contact lenses.Short sight up to -20 dioptersLong sight up to +8 dioptersCylindrical power up to +/- 6 diopters

Refrative Surgery deals with the correction of myopia / astigmatism / hyperopia for cosmetic or therapeutic reasons. Refrative service started in 1993 with inauguration of Summit Appex Plus Excimer laser for correction of myopia , hyperopia and astigmatism. In addition to this, the Excimer laser also helps in the management of corneal scars, spereoidal degeneration. In 2000, Hansatome was added to the refrative service for perfoming Lasik. The other refrative modalities include clear lens extraction for extreme myopia, wound revision and compression sutures.
