Abstract Details



Purpose:

The aim of this research was to make sure the effect of lens implantation intraoperative posterior capsular polishing and completely sucked viscoelastic agents on the rear of the intraocular lens for posterior capsule opacification(PCO) during cataract phacoemulsification. We want to explore preventive role for clinical improve surgical techniques and reduce capsular opacification occurs.

Setting:

Department of Ophthalmology, the Second Hospital Affiliated to Anhui Medical University, Hefei, PR China

Methods:

173 patients were selected from January 2011 to December 2011 in our hospital who was suffering senile cataract and needed a surgery (243 eyes), including 85 male patients (124 eyes) and 88 female patients (119 eyes). All patients preoperative visual acuity was light perception to 0.4. Aged form 50 to 79, the average (67.97 ± 6.71) years old. The patients were randomly divided into three groups A, B, C. Group A (control group): the conventional phacoemulsification technique: no capsular polishing, no suction behind the IOL viscoelastics. Group B (polished group): capsular polishing conventional phacoemulsification technology and surgery but did not suck addition to the IOL rear viscoelastics. C group (polishing group + IOL the viscoelastics suction group): conventional phacoemulsification technology and intraoperative capsular polishing, completely sucked viscoelastics behind the IOL group. Were followed up for three groups of patients with visual acuity and posterior capsule opacification and used for statistical analysis and comparison.

Results:

No intraoperative complications in three groups of patients, one week, 1, 3 months line of best-corrected visual acuity groups vision distribution was no significant difference. After 12 months, A group of 24 eyes occurs posterior capsule opacification, accounting for 41.96%. B group, 14 eyes, accounting for 16.88%, C group after capsular opacification 3 eye, accounting for 3.80%. Group C posterior capsular opacification occurred within 6 months after surgery, 2 patients one year follow-up, posterior capsule opacification alleviate. After six months, the group of PCO grading difference was statistically significant (P <0.001). Between group A and group B PCO grading difference was statistically significant (P <0.017), group A and group C, the difference was significant ((P <0.001), B group and C group differences no statistically significant (P = 0.094) after 12 months, each group PCO grading difference was statistically significant (P <0.001), the A group and B group difference was statistically significant (P <0.017), B group and C group difference was statistically significant (P = 0.001), group B and group C, the difference was not statistically significant (P <0.017).

Conclusions:

Posterior capsular cataract intraoperative the film polished and completely sucked addition to the posterior chamber IOL viscoelastic agents can be effective in reducing postoperative incidence of capsular opacification. FINANCIAL INTEREST: NONE
