Abstract Details

Purpose:

To report the outcomes of PRESBYOND Laser Blended Vision in ophthalmologists.

Setting:

London Vision Clinic, London, UK

Methods:

This was a retrospective study of 16 ophthalmologists who underwent PRESBYOND Laser Blended Vision treatments using the MEL 90 excimer laser and VisuMax femtosecond laser (Carl Zeiss Meditec). A comprehensive preoperative examination was performed to determine suitability for corneal laser refractive surgery and to exclude the need for cataract surgery by slit-lamp examination of the lens, Pentacam densitometry, and HD Analyzer optical scatter index (OSI). Postoperative follow-up visits were conducted at 1 day, 1 month, 3 months and 12 months. Standard outcomes analysis was performed using the data at the last visit.

Results:

At the time of analysis, 12 months follow-up was reached in 50% and 3 months in 50% of patients. Mean age was 56±8 years (42 to 76 years). Attempted SEQ was -4.88 to +3.50 D (mean±SD: +0.47±2.31 D). Cylinder was 0.00 to -2.00 D (mean±SD: -0.65±0.44 D). Preop CDVA was 20/20 or better in 94% of eyes and 20/16 or better in 78% of eyes. A retreatment was performed at 5 months for 1 patient. Six patients had previous ocular surgery; 4 LASIK, 1 cataract, 1 CK. For all patients, binocular UDVA was 20/20 or better in 88% and 20/25 or better in 100% of patients. Binocular UNVA was J1 or better in 88% and J2 or better in 100% of patients. Mean postop SEQ relative to the target was -0.12±0.35 D (-0.63 to +1.00 D), with 85% within ±0.50 D. There was 1 line loss CDVA in 15% of eyes, and no eyes lost 2 or more lines CDVA. There was no change in contrast sensitivity at 3, 6, and 12 cpd, and a statistically significant increase at 18 cpd.

Conclusions:

Treatment by PRESBYOND Laser Blended Vision enabled presbyopic ophthalmic surgeons to achieve excellent binocular vision at all distances without compromise to quality of vision and avoiding the increased risks and lower refractive accuracy of intraocular lens surgery while preserving contrast sensitivity.
