The efficacy of small incision non-phacoemulsification cataract intraocular lens implantation treatment of cataract with high myopia

Objective To analyze the efficacy of small incision non-phacoemulsification cataract intraocular lens implantation treatment of cataract with high myopia retrospectively.Methods A total of 62 cases (74 eyes) of high myopia with cataract received small incision cataract extraction and intraocular lens implantation and were followed up for 1 month to 3 months.One day,1 week,and three months were observed postoperatively.Visual acuity,refractive changes and related complications were analyzed.Results (1) Visual acuity:65 eyes (87.8％) corrected visual acuity better than preoperative.After three months,in the axial length less than 30mm group (51 eyes),corrected visual acuity was greater than or equal to 0.3,18 (35.3％) less than 0.02-0.3,20 (39.2％) less than or equal to 30mm group (14 eyes).The above vision standards,the number of eyes were 3(21.4％),9(64.3％),2 (14.3％).(2) Postoperative complications:6 eyes (8.2％) had poster capsule rupture,38 (58.4％) displayed corneal edema,8(12.3％) temporary high intraocular pressure.Postoperative astigmatism:From 74 eyes,preoperative and postoperative one day in January,March,measured mean comeal astigmatism were (2.43±0.72)D,(0.75±0.21)D,(0.52±0.33)D,(0.50±0.31)D.Preoperative and postoperative astigmatism was statistically significant (P ＜0.05),had no significant difference in the postoperative period corneal astigmatism between (P ＞0.05).Conclusions Small incision non-phacoemulsification cataract intraocular lens implantation treatment of cataract with high myopia has good postoperative recovery of visual function,can be used as phacoemulsification routine supplementation technique.
