Aphakia Correction by Injection of Foldable Intra Ocular Lens in the Anterior Chamber

Abstract

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student’s paired t-test was carried out to compare pre-operative and post-operative visual acuity (VA) and intraocular pressure (IOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean log-MAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively (P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.

Anterior Chamber Foldable Intraocular Lens for Correction of Aphakia

“…This change in IOP was not statistically significant (P=0.32). It was also reported in other similar studies [1][2][3] in which other approaches were used to correct aphakia. Two cases (10%) with pupil distortion were observed postoperative, which was also noted, in another study (2).…”

“…In complicated cases with insufficient capsule and lost zonular support it is not possible to insert a posterior chamber intraocular lens (PC IOL) [2]. Several techniques including posterior chamber sclera fixed lens, anterior chamber sulcus supported lens and anterior chamber iris claw lens have been reported to result in good visual out¬come in the management of aphakic eyes without capsular support [3]. The polymethylmetacrylate (PMMA) ante¬rior chamber (AC) intraocular lens has long been considered as a standard method of aphakia correction.…”

The Correction of Aphakia Using Anterior Chamber Intraocular Lens

“…The observed complications included intraocular hypertension (over 21 mmHg) in 14.3% of the patients, macular oedema (5%), pupillar ovalization (5%), and retinal detachment (5%). They concluded that an angular support foldable lens in the AC is a useful technique for the correction of aphakia in eyes without capsular support (37). The application of a new foldable foldable acrylic AC IOL (Acri.Lyc 15A, Acritec) through a small incision has also been found to result in increased visual acuity, being accompanied by several complications.…”
