EXPERIENCE THE NATURAL VISION IN MINUTES WITH LASER VISION CORRECTION – LASIK

Laser Vision correction or Lasik takes you from wearing glasses or contact lenses to clear natural vision in a matter of minutes.

At Rushabh Eye Hospital & Laser Center, we usie one of the most technologically advanced and state of the art VISX STAR S4 IR Excimer Laser Systems to offer you the best Lasik procedure. It is the first and only Lasik machine in Mumbai to offer custom vision correction with Iris registration. The advantage for you is that you will achieve exceptional visual clarity. This Laser System can accurately and safely treat spectacle numbers from +6.0 to -14.0. It is the most preferred technology for refractive surgeries worldwide because it ensures superlative laser delivery & clinical outcomes so that you are gifted with an even better, sharper vision than with glasses or contact lenses.

PROCEDURE:

As shown below, a thin protective flap of corneal tissue is folded back. The Excimer laser then reshapes tissue from the inner cornea to correct the refractive error with exceptional accuracy. The corneal flap is then replaced in position where it bonds.

KERATOCONUS

Keratoconus is a bilateral progressive disorder that affects the cornea: the clear outer surface of the eye, which allows light to enter the eye & focus on the retina. The cornea consists of finely arranged layers of connective tissue called collagen that constitutes up to 90% of its substance. The chemical bonds (cross links) in between these layers get weaker in keratoconus leading to progressive thinning and stretching of the cornea. Normal pressure within the eye causes the cornea to bulge forward to the shape of an irregular cone.

In the early stages, keratoconus, rigid, gas permeable contact lenses can be tried. In progressive cases, however, corneal collagen cross-linking is the treatment of choice.

CORNEAL COLLAGEN CROSSLINKING WITH RIBOFLAVIN (C3-R)

A new non surgical, non invasive treatment, based on collagen cross linking with Ultraviolet A (UVA, 365nm) and riboflavin (Vitamin B 2), a light-intensifying agent is now available. This changes the inherent properties of the cornea, increasing its mechanical strength. This increase in corneal strength has shown to arrest the progression of keratoconus.
The operative treatment is performed under totally sterile conditions. One eye per procedure must be treated, which requires the use of anesthetic eye drops. The surface of the eye (cornea) is treated by applying Riboflavin eye drops for 30 minutes. The eye is then exposed to UVA light for 30 minutes. Then, eye drops are applied; a bandage contact lens may be applied, which is removed during the follow-up visit. The main aim of this treatment is to interrupt the progression of keratoconus, and prevent further deterioration of vision, and the subsequent need of corneal transplantation.

CORNEAL TRANSPLANTATION

Corneal Transplantation is one of the most successful organ transplant surgeries. Diseased cornea can now be replaced successfully by transplanting a human donor’s cornea to the diseased eye. Replacing the unhealthy cornea with a healthy cornea is the only way of restoring vision.

A) PKP – PENETRATING KERATOPLASTY FOR OPTICAL AND THERAPEUTIC PURPOSES

Corneas for transplant come from individuals who have donated their eyes for use after their death, when they are free of transmissible diseases such as HIV, Hepatitis and Syphilis. The donor cornea is screened before being temporarily stored in a nutritive medium.

The donor cornea is secured on the patient’s eye with fine thin sutures made of nylon; about 8 to 16 sutures are put. These sutures can be removed later on after a period of 3 to 6 months. The corneal transplant procedure can be combined with cataract surgery and lens implantation when it is called “triple procedure”.

The success rate of corneal transplantation procedures is over 90%. In most cases, the patient is required to undergo regular, post-operative follow-up to ensure a better management of complications. The most common cause of failure of this procedure results from graft rejection, which can be successfully managed if treated at an early stage.

B) LKP: LAMELLAR KERATOPLASTY CORNEA TRANSPLANTS

The cornea is a transparent dome shaped structure that covers the front of the eye. It was known to consist of 5 layers until recentlym when a 6th layer called Dua’s layer was added to the list.
The cornea is peculiar in that it does not have any blood supply and hence is the only structure of the eye that can be transplanted.
Traditionally, corneal transplants involved removing the full thickness of the affected person’s cornea, and replacing it with a healthy donor cornea.
With advances in surgical techniques, the cornea can be divided into atleast 2 parts – the front and back being used for different indications. This is called Lamellar Corneal Surgery. The biggest advantage of lamellar surgeries are that since only a part of the donor cornea is implanted, the chances of rejection are much lower.

DSEK OR DESCEMET’S STRIPPING ENDOTHELIAL KERATOPLASTY

This procedure involves replacing the patient’s affected endothelium (the innermost layer of the cornea) with a healthy one from a donor cornea.

DALK OR DEEP ANTERIOR LAMELLAR KERATOPLASTY

It involves removing the outer layers of the damaged cornea and replacing them with corresponding healthy layers from a donor cornea.
Depending on the extent of damage to the patient’s cornea, and how much the layers are affected, the corresponding procedure amongst those.
