Abstract:
Purpose:To evaluate the visual outcome after cataract operations in high myopia patients, whose axial length differences are longer than 2 mm.
Methods:A retrospective study was conducted on patients who had received phacoemulsification cataract surgery from January 2014 to June 2020. The patients whose axial lengths and inter-eye axial lengths exceeded 26 and 2 mm, respectively, were selected. Demographic data, axial lengths, central subfield macular thickness, retinal nerve fiber layer, and best-corrected visual acuities (BCVAs) before and at 6 months postoperatively were collected. The factors related to visual outcome were analyzed using univariate, multivariate linear regression.
Results:Twelve patients had an inter-eye axial length difference longer than 2 mm. The average axial lengths of longer and shorter eyes were 29.17 ± 1.94 and 26.66 ± 2.51 mm, respectively (p = 0.02, Mann-Whitney U-test). The BCVAs (logarithm of minimal angle of resolution, logMAR) of the longer and shorter eyes before the surgery were 1.09 ± 0.62 and 0.19 ± 0.16, respectively (p = 0.03, Mann-Whitney U-test). The BCVAs (logMAR) of the longer and shorter eyes 6 months after surgery were 0.19 ± 0.16 and 0.08 ± 0.10, respectively (p = 0.11, Mann-Whitney U-test). In univariate linear regression analysis, the BCVAs 6 months after the surgery showed better preoperative BCVAs (p < 0.001) and a thinner central subfield macular thickness (p = 0.001). In multivariate linear regression analysis, the BCVA at 6 months after the surgery showed significant improvement compared with preoperative BCVA values (p < 0.001).
Conclusions:High myopia patients whose axial length differences exceeded 2 mm showed improved VA after cataract surgery.
