ABSTRACT

AIM: To observe the efficacy and safety of modified four-point fixed intraocular lens suspension implantation in aphakic eyes.METHODS:A prospective study. A total of 32 aphakic patients(32 eyes)with an average age of(44.56±8.48)years who underwent modified four-point fixed intraocular lens suspension implantation in our hospital from October 2020 to May 2021 were selected. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), corneal astigmatism, intraoperative and postoperative complications were observed before and after operation.RESULTS:The mean follow-up of all patients was(4.84±0.64)mo. The preoperative UCVA(LogMAR)was 1.25±0.42 and the last follow-up was 0.5±0.25(P<0.001). The preoperative BCVA(LogMAR)was 0.41±0.19 and the last follow-up was 0.42±0.19,(P >0.05). The preoperative corneal astigmatism was(1.17±0.64)D and the last follow-up was(1.20±0.59)D(P>0.05). There were no intraoperative complications, but 2 eyes had low intraocular pressure, 1 eye had high intraocular pressure and 2 eyes had corneal edema occurred after operation. There were no complications of hyphema, vitreous hemorrhage, macular cystoid edema, corneal endothelial decompensation, inclination or eccentricity of intraocular lens and exposure of suture.CONCLUSION:The modified four-point fixed intraocular lens suspension implantation can significantly improve the postoperative visual acuity of aphakic patients without additional corneal astigmatism,and with fewer complications.
