Introduction Ø LASIK : Laser-Assisted In-Situ Keratomileusis Ø Form of Refractive Surgery Ø Reduces/Eliminates need for eyeglasses & corrective lenses Ø Corrects: -Myopia -Hyperopia -Astigmatsim
Brief History Ø 1950’s – Columbian Jose Barraquer developed Microkeratome & keratomileusis techniques and discovered root causes for eye trauma Ø 1970’s – Russian Svyatoslav Fyodorov developed Radial Keratotomy (and posterior chamber implantable contact lenses in 1980) Ø 1970’s – Development of Excimer Laser (origin of LASEK laser) Ø 1982 – 3 Members of the IBM research team discovered the laser could be used to remove biological tissue without heat damage to surrounding tissue Ø 1987 – Dr. Steven Trokel performed the 1 st laser surgery on a patients eye Ø 1996 – Lasik Eye Surgery cecame officially approved by the U.

Procedure
Procedure
Examples of Correction
Results Ø The surgery is typically done within 30 minutes or less -quick & painless Ø Most people achieve 20/20 vision (or even better) afterwards (90% reach desired vision after LASIK) Ø May still need glasses/contact lenses, but prescription is much lower than before Ø A small percentage of people have an enhancement (minor touch up) surgery later for further improved vision Ø Requires no bandages or stitches
Risks/Limitations Risks of Lasik Eye Surgery Limitations of Lasik Eye Surgery Ø Undercorrection Ø Results may not be permanent Ø Overcorrection Ø May still need glasses/contacts Ø Astigmatism Ø Effects non-reversible Ø Glare, Halos, & Double Vision Ø 2 -3 months for full recovery Ø Dry Eyes Ø Average cost $2000 per eye Ø Flap Problems Ø Can not be done for all eye types
Other Surgeries Ø Photorefractive keratectomy (PKR) Ø LASEK Eye Surgery Ø Phakic intraocular lenses (Phakic IOL)
Future Ø Improvements in acuity of laser Ø More accurate calibration techniques/equipment to avoid too much or too little tissue removal Ø Faster Recovery Rate Ø Lower Price Ø The ability to undergo surgery at a younger age
