Refractive surgery refers to removal of eye’s refractive error by laser method. The modern surgical method is LASIK (laser in situ keratomileusis) and involves first creating a thin flap of around 100 micron on the surface of the eye with either a femtosecond laser or a microkeratome. This upper layer or flap is then moved to one side to allow the surgeon access to the cornea. Then the surgeon uses the excimer laser to accurately reshape the cornea and treat the refractive errors of the eye. Then the created flap is reclosed.
Refractive errors include myopia, hypermetropia, and astigmatism. Presbyopia, the far-sightedness, occurs at the age of 40 to 45 years old can be corrected by LASIK, a new method. TECHNOLAS 217P at our clinic is able to correct all refractive errors listed above and includes a presbyopia module. Any refractive errors of a patient can be corrected by this device.
Your refractive error needs to remain unchanged for 6 months and some of your corneal tests must be positive if you intend to have a LASIK surgery. Prior to LASIK, we have a special screening including TECHNOLAS Wavefront screening system, and aberrometer and orbscan techniques. In addition to refractive errors mentioned above, this screening program is used to map all physical features such as physical light deviations, corneal thickness, refractivity and obliquity. This system provides information on whether the patient is suitable for LASIK.
LASIK is a method performed successfully at our clinic by a refractive surgeon using the latest technology.
