LASIK & Refractive Surgery
NOT SUITABLE FOR LASIK?
YOU CAN STILL FIND YOUR WAY TO GREAT EYESIGHT.
It is generally believed that LASIK is the only way to get rid of your glasses. Sometimes LASIK may not be possible, especially if you have thin corneas or unusually high power in your eyes.
Well, there's no need to worry. There are many other advanced and safe solutions for those who want to have perfect glass-free eye sight.
EPI-LASIK FOR SURFACE PRK
Epi-Lasik surface Photorefractive Keratectomy (PRK) is an alternative to LASIK for the correction of near sightedness, far sightedness and astigmatism in candidates with thin corneas. In this procedure, an extremely thin sheet of corneal epithelium is removed to allow laser ablation, thereby saving more corneal tissue. The epithelium grows back in two to three days. The deeper corneal tissue need not be cut or harmed while performing this laser surgery.
SUB BOWMAN’S KERATOMILEUSIS
Sub Bowman’s Keratomileusis (SBK) uses the Intralase Femtosecond Laser to create a 90 micron flap which is thinner than a typical LASIK flap. By making such a thin and precise flap, SBK enables a correction of higher powers in thinner corneas. There is faster visual recovery and the risk of ectasia is minimized. SBK combines the advantage of PRK with quick recovery time of LASIK.
IMPLANTABLE CONTACT LENSES
Think of it as a contact lens, but a more permanent one. Implantable Contact Lenses or ICL are lenses which are implanted into your eyes between the iris and the natural lenses. These lenses are made up of a biocompatible collagen co-polymer called COLLAMER and have extremely high water content. Therefore they cause no discomfort to the patients. ICLs are implanted in patients who need correction for very high powers that exceed the safe range of excimer laser procedures such as LASIK.
REFRACTIVE LENS EXCHANGE
LASIK is essentially a procedure where the cornea is reshaped to give better vision. What if the cornea is too thin? In that case, instead of treating the cornea, it would be a better idea to treat the lens. That is exactly what is done in Refractive Lens Exchange. The surgeon removes the natural crystalline lens and implants an accommodative or multifocal lens, which provides the range of vision required for spectacles free vision.
COLLAGEN CROSS LINKING
Collagen Cross Linkage or C3R stabilizes and strengthens the cornea is patients with keratoconus or other forms of thinning disorders. The surgeon administers special riboflavin drops and provided UVA radiation the cornea to cross link fibers. These crosslinked collagen fibres strengthen the cornea. This is a permanent treatment and the only way to stop the progression of keratoconus. C3R may be combined with INTACS to correct the refractive error.
Intrastromal Corneal Ring Segments or INTACS is another great option for patients with keratoconus and for those suffering from moderate myopia (short sightedness). These implants preserve the cornea’s natural shape and can be replaced r removed as your future correction needs change.
CHOOSING THE RIGHT PROCEDURE
To choose the procedure which fits you best, consult your eye care specialist. He or she will do a detailed examination and explain the advantages and disadvantages of each of these options as pertaining to your particular case.
All this is to ensure that you get the best care possible because every eye deserves the best.
