The microkeratome is a very precise instrument that cuts the cornea into a thin cap with predetermined thickness. The Excimer Laser machine emits cool beam of invisible ultraviolet light to vaporize certain portion of corneal tissue. The whole procedure is under strict and precise computer control and therefore can correct refractive errors in a predictable way.
The principle of most refractive surgery is to change the curvature of cornea, in order to correct refractive errors. LASIK surgery involves two steps: Corneal flap cutting and laser treatment. These procedures are performed under high magnification with an operating microscope. Firstly a thin cap of corneal tissue is cut with the corneal cutting machine (microkeratome). The cap is then lifted and second step is to apply Excimer Laser to the corneal bed. The cap is re-positioned after the laser treatment. The cornea has amazing natural bonding qualities, and the flap can adhere to corneal bed almost immediately after the cap is re-positioned and no suture is necessary .
The procedure only takes 10 minutes for each eye. The advantages of LASIK surgery are fast vision recovery, less discomfort postoperative and few complications. If you want to reduce dependency on glasses or contact lens, LASIK surgery would be a good option for you. It has made enormous difference to many people that had to rely on visual aids. It is a difference that helps them achieve visual freedom and improves their quality of life and vision.
Cataract surgery is one of the most successful surgical operations. About 95% of those received cataract surgery have improved vision.
The latest Phacoemulsification is to apply ultrasound technology to remove cataract and replace it with an artificial lens. This new procedure creates an incision a mere 2 mm which results in safer and quicker recovery.
