AIM: To evaluate the efficacy and safety of non-astigmatism posterior chamber implantable intraocular lens in the correction of high myopia with moderate astigmatism.

METHODS: This retrospective study included 31 patients(44 eyes)with high myopia and moderate astigmatism who had posterior chamber intraocular lens(V4c)implantation surgery in our hospital from December 2013 to December 2015(astigmatism in the range of -1.00 to -2.00D). The last follow-up time was 14.52±2.40mo. Visual acuity, intraocular pressure, anterior chamber depth, corneal endothelial cell density, vault, complications, patient satisfaction, etc. were observed pre- and postoperative.

RESULTS: At the last follow-up, the effective index of this group was 1.38±0.35, the safety index was 1.42±0.30. The uncorrected visual acuity and corrected visual acuity(LogMAR)was better than preoperative(0.05±0.15 vs 1.48±0.29; 0.03±0.12 vs 0.18± 0.15; all P<0.05), the anterior chamber depth was lighter than preoperative(2.22±0.28mm vs 3.19±0.20mm, P<0.05), and there was no difference between intraocular pressure and corneal endothelial cell density(P>0.05). At the last follow-up, no serious eye complications occurred in this group, and the total satisfaction was 94%.

CONCLUSION: Non-astigmatic posterior chamber implantable intraocular lens is a safe and effective solution for high myopia with moderate astigmatism.
