LASER VISION CORRECTION

 

Bharti Eye Foundation was at that point a famous place for nearsightedness revision medical procedure beginning around 1987 and procured the Excimer laser in 1995 and first LASIK was acted in Delhi in November 1995 by Dr.S.Bharti.

 

Laser vision correction techniques are

1. Contura, PRK or Photo Refractive Keratectomy (Surface treatment, contura vision) this is the oldest  techniqe of vision correction beginning around 1995

6. Z-LASIK or Femto-LASIK is further developed ALL LASER LASIK wherein the fold of 90µ is made with a Femtosecond LASER and the laser revision depends on ABERRATION GUIDED innovation to address the power permitting significantly higher remedy with more exactness because of synchronous rectification of fine micron level distortions.
