Abstract
Background: In microspherophakia, abnormal laxity of the lenticular zonules leads to development of a
spherical lens and possible subluxation. We evaluated long-term results of lens removal with scleral-fi xated
intraocular lens (SFIOL) implantation in microspherophakia. Materials and Methods: Case series. SF IOLs
were implanted in four consecutive patients with bilateral microspherophakia (eight eyes [three with
pupillary block and secondary glaucoma who underwent immediate surgery and fi ve with only subluxation
who underwent elective surgery]). Post-operative best-corrected visual acuity (BCVA), intraocular
pressure (IOP) and lens position were evaluated periodically from day 1 to 18 months. Results: All patients
were females (mean age 28 ± 7.03 years). In group 1 eyes (three eyes that presented with pupillary block),
the mean BCVA improved from 0.008 decimals (preoperative) to 0.50 decimals (fi nal post-operative visit);
in group 2 eyes (the other fi ve eyes), the mean BCVA improved from 0.12 ± 0.21 decimals to 0.73 ± 0.14
decimals. The preoperative mean IOP (54.53 ± 7.33 mmHg) in group 1 eyes was signifi cantly (P = 0.03) higher
than that (16 ± 4.30 mm Hg) in group 2 eyes. At fi nal post-operative visit, the mean IOP (11.67 ± 2.88 mmHg)
in group 1 eyes was not signifi cantly diff erent from that in group 2 eyes (13.0 ± 3.08 mmHg). All SFIOLs
were well- centred at the fi nal visit. None of the patients encountered any peroperative or postoperative
complications. Conclusions: SFIOLs may be an option for surgical management of microspherophakia.
