ABSTRACT
Objectives:
To compare the visual prognosis and postoperative complication rates of secondary anterior chamber (AC IOL) and scleral-fixated (SF) intraocular lenses (IOL) after complicated phacoemulsification surgery.
Materials and Methods:
Thirty eyes of thirty patients were reviewed for this retrospective study. The patients with secondary AC IOL implantation formed group 1 (n=15), and the patients with secondary SF IOL implantation formed group 2 (n=15). Best-corrected visual acuity (BCVA) with Snellen chart, biomicroscopic examination, intraocular pressure (IOP) measurement with applanation tonometer, gonioscopy performed by Goldmann’s 3-mirror contact lens, and fundus examination were performed preoperatively in all patients.
Results:
There was no statistically significant difference in postoperative BCVA (p=0.492) and postoperative success (BCVA not changed or better postoperatively) between the 2 groups (p=0.598). Postoperative success rate was 80% in group 1 and 93.7% in Group 2. The postoperative cylindrical power of the eyes did not differ significantly between the groups (p=0.220). The postoperative complications in group 1 were as follows: transient corneal edema in 5 eyes, transient IOP elevation in 2 eyes, postoperative fibrinous reaction in the anterior chamber in one eye, late-onset secondary glaucoma in one eye, hyphema in one eye, cystoid macular edema in one eye, vitreous prolapse into the anterior chamber in one eye, and IOL malposition in one eye. The postoperative complications in group 2 were as follows: transient corneal edema in 3 eyes, vitreous prolapse into the anterior chamber in 2 eyes, IOL malposition in 2 eyes, transient IOP elevation in one eye, and retinal detachment in one eye.
Conclusion:
In this study, both IOL types were observed to be preferable in cases without adequate capsular support following complicated cataract surgery. However, further studies with large numbers of patients are needed to define the best choice of IOL in patients with inadequate capsular support.
