Effect of haptic material and number of intraocular lens on anterior capsule contraction after cataract surgery

Abstract

Purpose: To evaluate changes over time of the anterior capsule opening size after phacoemulsification, based on haptic number and composition of three acrylic intraocular lenses (IOLs).

Methods: Fifty-five patients (70 eyes) were included. All underwent phacoemulsification followed by implantation of either an acrylic IOL with two-haptic (one-piece, 26 eyes; three-piece, 22 eyes), or four-haptic (one-piece, 22 eyes). The area of the anterior capsule opening size was measured one week postoperatively (baseline) and at three months.

Results: There was a significant reduction in the area of the anterior capsule opening from one week as compared to three months postoperatively in all groups (p < 0.001). However, there was no significant difference in the reduction in the anterior capsule opening between the IOLs (p = 0.36).

Conclusions: The number and material of the haptic of the three acrylic IOLs did not influence the degree of anterior capsule opening shrinkage.

This graph shows postoperative changes in the area of the anterior capsule opening (ACO). The initial area of the ACO one week after surgery was not significantly different among the groups (p = 0.88). There was a significant reduction at three months compared to one week in all three groups (p < 0.001). However, there was no significant difference in ACO three months postoperatively among the three groups (p = 0.65). ^*Statistically significant (p < 0.05).
