Postoperative Refractive Outcomes Of Using Acrysof Ma60 3-Piece Iol In Vitrectomised Eyes

Accurate prediction of refractive outcomes following phacoemulsification is challenging in vitrectomised eyes with previously reported hyperopic/myopic variation post-operatively. We aim to assess refractive outcomes of using Acrysof MA60 3-piece IOL as a possible way of achieving more precise refractive outcomes in this group.

Retrospective data analysis using Medisoft Electronic Medical Records (EMR) of patients who had uncomplicated phacoemulsification with either combined pars plana vitrectomy (PPV) or previous PPV in the same eye with Acrysof MA60 3-piece IOL implantation. Exclusive criteria were history of refractive surgery, complicated cataract surgery, silicone oil in the eye or unsuccessfully RD repair. The postoperative refractive outcomes were compared with the Royal College of Ophthalmologists guidelines of a benchmark standard of 85% of individuals achieving a final spherical equivalent within 1.0D of the predicted refraction and 55% of individuals within 0.50D. Refractive surprise was defined as post-operative spherical equivalent deviation >1.0D.

From September 2019 to January 2022, 22 eyes met the inclusion criteria. All eyes had Acrysof MA60 3-piece IOL implanted in capsular bag. Overall, 86% of eyes were within 1.0D and 55% within 0.5D of target refraction postoperatively. The mean spherical equivalent deviation was -0.04 ± 0.73D (SD). Refractive surprise was identified in 14 % eyes. The spherical equivalent deviation was +1.50D, -1.25D, -1.76D respectively.

Postoperative refractive outcomes of using Acrysof 3-piece IOL in vitrectomised eyes met the national standards. Acrysof MA60 3-piece IOL possibly results in less refractive surprises, however, larger studies are warranted to address this as our cohort number was significantly impacted by the COVID-19 Pandemic.
