A 45-year-old woman complained of glare and photophobia after iris-fixated phakic intraocular lens (IFPIOL) implantation in her left eye. The patient underwent prophylactic laser peripheral iridotomies (LPIs) 2 days before surgery. The uncorrected visual acuity after surgery was 20/20 and the intraocular pressure was 14 mm Hg. The slit-lamp examination showed a well-centered IFPIOL and 2 LPIs at 10 and 2 o’clock partially covered by the upper lid. Twenty days after IFPIOL implantation, as symptoms persisted and were intolerable to the patient, we decide to suture iridotomies using a modified Siepser slip-knot technique. Postoperatively, visual acuity remains 20/20 and patient reported a complete disappearance of symptoms. No intraoperative and postoperative complications were noted. Experiencing glare and photophobia is a rare side effect due to LPI. Suture of iridotomies using a modified Siepser slip-knot technique can be considered a safe and effective procedure to solve this annoying complication.
