Purpose
To evaluate visual and refractive outcomes of IOL implantation during phacoemulsification of cataract in amblyopic eyes of adults with high hyperopia.
Setting
the investigation was conducted from January 2022 to December 2023 in the microsurgery eye department of Zaporizhzhia Regional Clinical Hospital, Ukraine
Methods
Cataract surgery was performed first on the amblyopic eye. Visual acuity and refractive outcomes on the amblyopic eye were evaluated 1 month after the surgery. Group 1 comprised 34 eyes with amblyopia, where corrected distal visual acuity (CDVA ) on the amblyopic eye was equal to the CDVA on the dominant eye. Group 2 consisted of 22 eyes with amblyopia, where corrected distal visual acuity (CDVA ) on the dominant eye was higher then on the amblyopic eye. Exclusion criteria was presence of ocular pathology other than cataract. Toric IOL was implanted in all cases with more than 1,0 D in the rule astigmatism and more then 0,75 against the rule astigmatism
Results
Retrospective analysis of 56 eyes with hyperopia and amblyopia who underwent cataract surgery was conducted. Axial length on the amblyopic eye of the first group was 20,9±0,19 mm and 20,6±0,21 mm in the second group, on the dominant eye 21,72±0,09 mm and 21,81 respectively. CDVA on eye with amblyopia increased significantly in group 1 from 0,3±0,01 before surgery to 0,8±0,02 (P≤0,001). An improvement of CDVA occurred in all eyes (100%). CDVA on the dominant eye of this group was 0,37±0,02. Improvement of CDVA on the eye with amblyopia in the group 2 was from 0,3±0,02 before surgery to 0,5±0,03 (P≤0,001). CDVA on the dominant eye of this group was 0,84±0,02.
Conclusions
Cataract surgery in patients with high hyperopia and amblyopia leads to significant improvement of visual functions. Postoperative visual acuity after IOL implantation on the amblyopic eye depends on the preoperative difference between eyes and much better in cases where dominant eye had visual acuity equal to the amblyopic eye
