Laser Blended Vision-LASIK for Presbyopia and Initial Clinical Experience in 100 Indian Patients.

ABSTRACT

Aim: The aim was to study the visual results of laser blended vision (LBV), (LASIK with a nonlinear aspheric micromonovision protocol) for presbyopia correction. Materials and Methods: Binocular and uniocular vision and postoperative outcome of 100 patients undergoing LBV were studied. The study included myopes (−0.25 to −7.25 DS), hypermetropes (+0.25 to +4 DS) and emmetropic presbyopes between ages 39 and 55 years (mean 47) with a minimum follow-up of 6 months. Results: Binocular distance vision 83% read 6/6 or better, 100% read 6/9 or better at 6 months. Near vision 96% read near n6, remaining read n8. All patients had an intermediate vision (n6). An adaptation rate of more than 95% within first 3 months was noted without significant loss of visual acuity due to the procedure. Conclusion: LBV may be a safe approach to presbyopic LASIK treatment with high adaptation rates. Long-term studies are needed to establish the stability of treatment results over time.
