ABSTRACT

AIM: To evaluate the effect of anterior capsule polishing on visual quality after phacoemulsification.METHODS: Prospective randomized control study. A total of 65 patients(73 eyes)with age-related cataract who underwent phacoemulsification combined with intraocular lens(IOL)implantation in the Emergency General Hospital between November 2021 and June 2022 were included. These patients were randomly assigned to two groups, with one group(anterior polishing group)underwent anterior and posterior capsule polishing(30 cases, 35 eyes), while the other(control group)receive routine posterior capsule polishing(35 cases, 38 eyes). Best corrected visual acuity was observed at 1wk, 1, 3 and 6mo after operation. Area of anterior capsule orifice was measured at 3 and 6mo after operation. Meanwhile, posterior capsular opacification(P score), IOL tilt and decentration were recorded by Pentacam Scheimpflug system. In addition, wavefront aberration, Strehl ratio(SR)of point spread function(PSF)and modulation transfer function(MTF)were evaluated by OPD-Scan Ⅲ.RESULTS: At 1wk, 1, 3 and 6mo after operation, best corrected visual acuity in anterior polishing group is significantly better than that of control group(P<0.05). There were no significant differences in area of anterior capsule opening, P score, IOL decentration, SR of PSF and MTF between two groups at 3 and 6mo after operation(P>0.05). At 3mo follow-up, no significant differences in IOL tilt and wavefront aberration were measured between two groups either(P>0.05). However, IOL tilt [(1.65±0.60)° vs.(2.34±0.43)°, P<0.001] and wavefront aberration(0.03±0.01μm vs. 0.06±0.03μm, P<0.001)in anterior polishing group were significant lower compared to control group at 6mo after operation.CONCLUSION: 360° polishing of anterior and posterior capsule during phacoemulsification can improve best corrected visual quality, with reduced IOL tilt, lower wavefront aberration and better visual quality.

ABSTRACT

@#AIM: To investigate the effect of fine capsule treatment on the visual quality of diffractive multifocal intraocular lens.<p>METHODS: Ninety-eight patients(120 eyes)with DMIOL implanted in cataract Department of Hebei Eye Hospital from March 2017 to April 2018. They were randomly divided into A group and B group. 60 eyes in each group. Group A patients were treated with anterior and posterior capsular polishing and posterior continuous circular capsulorhexis, while in B group the fine capsule treatment was not performed. The UCDVA, UCIVA, UCNVA, visual quality, intraocular lens neutrality and PCO incidence were compared 6mo after operation.<p>RESULTS: At 6mo after operation, UCDVA, UCIVA and UCNVA in group A were superior to those in group B. The difference was statistically significant(<i>P</i><0.05). At 6mo after operation, the amount of eccentric intraocular lens in group A was less than that in group B. The difference was statistically significant(<i>P</i><0.05). PCO incidence: group A: 0 eyes; group B: 5 eyes(8.3%)in gradeⅠ, 3 eyes(5.0%)in grade Ⅱ, 2 eyes(3.3%)in grade Ⅲ.<p>CONCLUSION: In order to enhance the stability of IOL and maintain the long-term transparency of the optic axis, we performed fine polishing of the anterior and posterior capsule and continuous circular capsulorhexis of the posterior capsule. These could improve the visual quality and satisfaction of patients after surgery.

ABSTRACT

AIM:To evaluate the effect of all capsule polishing with polishing mode for decreasing the occurrence of posterior capsular opacification( PCO) . METHODS: Totally 194 eyes ( 162 patients ) were performed phacoemulsification, posterior chamber intraocular lens were implanted. One hundred eyes were performed with all capsule polishing with polishing mode;94 eyes were performed with the polishing apparatus. RESULTS:The patients were followed up for 12mo. Six eyes ( 6. 0%) of PCO were found in the 100 eyes with polishing mode group; 15 eyes ( 16. 0%) of PCO were found in the 94 eyes with the polishing apparatus group. The difference was significant (P CONCLUSION: It can decrease the occurrence of PCO by performing all capsule polishing with polishing mode.
