Preferred surgical techniques for secondary intraocular lens implantation in adults with aphakia.

AIM

To identify the current surgical management of aphakia and the outcomes and complications of each technique.

METHODS

This cross-sectional study included ophthalmic surgeons with at least one-year experience in surgery for aphakia. A study questionnaire was formulated to collect data in Saudi Arabia and other regional countries. The questionnaire included 22 questions on demographics, preferred surgical techniques, complications and the factors related to surgeon decision and the choice for managing aphakia.

RESULTS

The study included 145 participants (111; 76.6% were males) with mean age of 46.7 ± 11.5 years. The mean duration of cataract surgery experience was 17.6 ± 11.1 years. Most participants (86.2%) were trained in cataract surgery. Scleral fixation of intraocular lens (SFIOL) was the most commonly preferred technique, followed by iris fixation IOL, and anterior chamber IOL (75.2%, 9%, and 15.9%, respectively). The main determinants for selection of a surgical technique were simplicity (56.6%), surgical instrument availability (48.3%), and training on the technique (47.6%). The most frequent postoperative complications were pupil distortion, high intraocular pressure (IOP), pupillary capture of the IOL, and IOL decentration.

CONCLUSIONS

SFIOL is the preferred surgical technique for managing aphakia. The decision to choose one technique over another is complex and is based on several factors, including technical difficulty, previous training, anatomical variations, ocular comorbidities, and the potential complications. The most frequent complications after surgical correction of aphakia are pupil distortion, high IOP, pupillary capture of the IOL, and decentered IOLs.
