5M.D., Ankara Training and Research Hospital, Eye Clinic, Ankara/TURKEY Purpose: To evaluate the cause and outcomes of scleral-fixation intraocular lenses (SF-IOL) in patients with no adequate capsular support and younger than age of 15 years.
Material and Methods: The children who underwent SF-IOL and were followed-up at least 6 months were retrospectively evaluated according to the causes of SF-IOL implantation reasons, surgical outcomes and complications. Snellen chart was used to measure best corrected visual acuity (BCVA).
Results: Mean ages was 9.8±3.9 (4-15) years, 4 females and 13 males, 24 eyes of 17 patients were evaluated. The mean follow-up was 20.7±16.2 (6-52) months. SF-IOL surgery was performed as primarily operation in 14 eyes, as secondary operation in 10 eyes (6 aphakic and 4 lens exchange). 7 cases were bilateral. The etiologies of lens subluxation in 10 eyes, congenital cataract in 10 eyes, lens and iris coloboma in 2 eyes, microspherophakia in one eye and traumatic cataract in one eye. Postoperative complications included; retinal detachment in one eye, endophthalmitis in one eye, intraocular lens decentralization in one eye, irregular pupil in 3 eyes and elevated intraocular pressure in one eye. Preoperative BCVA less than 0.1 in 9 eyes, 0.1-0.5 in 12 eyes, better than 0.5 in one eye whereas postoperative BCVA less than 0.1 in one eye, 0.1-0.5 in 12 eyes, better than 0.5 in 9 eyes of 22 patients. Visual acuity measurements of two cases were unreliable.
Conclusion: SF-IOL implantation in children of different reasons, an effective method of providing permanent optical rehabilitation. Careful follow-up of patients is recommended for the development of complications.
