Ans. The visual acuity improvement is gradual, even taking upto 6 months or longer. This improvement is not dramatic as in LASIK or laser eye surgery, because the aim is not to improve visual acuity but to prevent further deterioration. Our earliest cases have been done in April 2007, hence it is still to early to comment on any significant data. However, all patients have shown arrest and no progress in the condition and some of our patients have had upto 2 lines of improvement in visual acuity. Many have shown actual improvement on their topography maps.
