LASER VISION CORRECTION SURGERY
The EXCIMER LASER uses two primary vision correction surgeries- PRK (Photo Refractive Keratectomy) & LASIK (Laser assisted In Situ Keratomileusis).
PRK involves removal of less than ten percent of the corneal tissue. It sculpts the surface of the cornea, changing its curvature.
Photo refractive keratectomy (PRK) combined with Laser Assisted In Situ Keratomileusis (LASIK) uses an instrument called Microkeratome to create a thin flap of corneal tissue. This flap is folded to the side and Excimer Laser is used sculpt the cornea. The Excimer Laser produces an invisible beam of intense ultraviolet light, delivered in short bursts of energy called pulses. The corneal flap is then replaced.
Who is eligible for LASIK?
What results can be expected?
The aim of the treatment is to remove dependence on spectacle or contact Lens wear.
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
Yes, preoperative corneal and retinal evaluation would have to be carried out.
Is it painful?
During the laser treatment, there is no pain at all. However you may experience some ocular discomfort and watering during the first 24 hours after surgery. It will gradually resolve by second or third day. Painkillers and sedatives may be prescribed to ease the pain and discomfort.
Will my number become zero?
The aim of the laser treatment is to remove dependence on spectacles or contact lenses or in many cases eliminate them altogether.
How long does it take to recover?
The surface of the cornea takes 2-3 days to heal and vision will improve thereafter. Stability in vision is achieved in 1-3 months.
When can I resume my normal activities?
Normal activities can be resumed after 1 week. However swimming and water sports can be resumed after 3 months.
When can I have my other eye done?
The second eye can be done immediately after the first eye in the same sitting or after 3 days.
