Clinical Outcomes Of Bilateral Cataract Surgery After Previous Presbyond Lbv Correction - A Case Series

Purpose: To present a case series of bilateral cataract surgery in patients who have  undergone previous Presbyond Laser Blended Vison (LBV) correction.

A retrospective case series of 4 patients who underwent cataract surgery in both eyes after previous Presbyond LBV at Nethradhama Superspeciality Eye Hospital

Methods: . Barrett True K formula was used for IOL power calculation with a plano target for dominant eye and  myopic target for the non-dominant eye based on the previous target refraction used for Presbyond surgery. Aspheric monofocal IOL was implanted, preserving the mini monovision. Aberrometry was done pre operatively and the spherical aberration was assessed. Post operative visits were conducted at day 1, day 15 and 3 months, where UDVA, UIVA, UNVA, CDVA, CIVA, CNVA, aberrometry, Ocular Scatter Index(HDA), and subjective questionnaire were assessed

Results:  At 3 months post operatively no eyes lost 2 or more lines of BCVA. 3 out of 4 patients had Binocular UDVA of LogMAR 0, UIVA of LogMar 0.2 at 60cm and UNVA of LogMar 0 at 3 months post operatively. 1 patient had UDVA of LogMar 0.1, UIVA of LogMar 0.18 and UNVA of LogMar 0.1 at 3 months. Spherical equivalent refractive accuracy in all  eyes  was within +/- 0.50DS of target refraction. No patients had change of more than 0.5D spherical equivalent from post operative day 1 to 3 months.

Conclusion: These results indicate that cataract surgery after Presbyond LBV can deliver good  visual outcomes for distance, intermediate and near vision with spectacle independence, effectively maintaining the benefits of the previous Laser Blended Vision treatment.
