Abstract
Purpose
To compare the results of sulcus implantation of acrylic and poly(methylmethacrylate) (PMMA) intraocular lens (IOL) in eyes with posterior capsule tear during phacoemulsification surgery.
Methods
In all eyes a posterior capsule tear developed during phacoemulsification surgery and an IOL to the ciliary sulcus was implanted primarily. A total of 89 eyes of 88 patients received hydrophilic foldable acrylic IOL (acrylic group). A total of 72 eyes of 72 patients received PMMA IOL (PMMA group). The mean age was 67.1 years and 68.1 years and postoperative follow-up period was 19.2 months and 17.9 months in acrylic and PMMA groups, respectively.
Results
Temporary corneal edema appeared in 33 eyes and 26 eyes, elevation of intraocular pressure in 17 eyes and 12 eyes, anterior chamber inflammatory reaction in 5 eyes and 5 eyes, clinical cystoid macular edema in 7 eyes and 12 eyes, and decentered IOL in 4 eyes and 3 eyes in acrylic and PMMA groups, respectively. Late postoperative endophthalmitis developed in two eyes of the PMMA group. Rhegmatogenous retinal detachment developed in one eye in each group. Final best-corrected visual acuities were 5/10 and above in 73 eyes (82.02%) in the acrylic group and 5/10 and above in 42 eyes (58.33%) in the PMMA group. Postoperative final induced astigmatism was 0.5±0.5 D (SD) in the acrylic group and 1.11±0.65 D (SD) in the PMMA group (p=0.0001) (independent samples t-test).
Conclusions
Increased astigmatism is more frequently seen in the PMMA group. The implantation of foldable acrylic IOL in the sulcus after posterior capsule tear maintains the advantages of small incision surgery.
