ABSTRACT

@#AIM:To study the curative efficacy of aspheric intraocular lens implantation after manual nuclear fragmentation in treatment of cataract and its effects on visual acuity. <p>METHODS: Totally 100 patients of cataract who received therapy from May 2013 to May 2016 in our hospital were selected. According to random number table, those patients were divided into the observation group(50 patients 68 eyes)and the control group(50 patients 67 eyes). The observation group was treated with small incision manual discectomy and aspheric intraocular lens implantation, the control group was treated with phacoemulsification cataract extraction and aspheric intraocular lens implantation, the operation effect of two groups were compared. <p>RESULTS: After operation, the corneal endothelial cell counts of the two groups decreased(<i>P</i><0.05); in the observation group, the results were higher than those of the control group at 1 and 3mo after operation(<i>P</i><0.05). In the observation group, the uncorrected visual acuity at 1mo after operation was better than that of the control group(<i>P</i><0.05); there was no significant difference between the two groups in postoperative visual acuity after operation 3mo(<i>P</i>>0.05). At 1mo after surgery, the corneal astigmatism in the observation group was higher than that of the control group(<i>P</i><0.05); there was no significant difference of corneal astigmatism between the two groups at 3mo after operation(<i>P</i>>0.05). The incidence of intraoperative complications and postoperative complications in the observation group were lower than that of the control group(<i>P</i><0.05). <p>CONCLUSION: Aspheric intraocular lens implantation after manual nuclear fragmentation is well for cataract, which can reduce the damage to corneal endothelial cells, the complications rate is low and the postoperative visual acuity recovered well.
