Xtra focus pinhole IOL (Morchers GMBH) a novel approach to tackle irregular astigmatism and large pupillary defects with a single step surgery.

Abstract

A 69-year-old patient presented to us with traumatic mydriasis with irregular pupil measuring 7 mm, with superior loss of iris tissue and large inferior peripheral iridotomy and pseudophakia. The patient had history of blunt trauma 3 years ago in a fire cracker injury. He was operated elsewhere primarily after the trauma for cataract surgery with intraocular lens implantation and had suboptimal visual outcome with glare and photophobia. He presented to us with irregular pupil and inferior iridectomy with pseudophakia. The uncorrected visual acuity was 20/150 improving to 20/50 with glasses. He had a history of cataract surgery with intraocular lens (IOL) implantation done elsewhere several years back. The patient was not a diabetic or hypertensive. There was a para central corneal scar causing irregular corneal astigmatism. Extra focus pinhole IOL was implanted in sulcus having a pinhole aperture 1.36 mm. Preoperative total corneal higher-order aberrations were 3.3 µ and total corneal coma was 0.97 µ. Postoperatively uncorrected distance visual acuity improved to 20/40 intermediate uncorrected visual acuity improved to 20/30 and uncorrected near visual acuity was J3. © BMJ Publishing Group Limited 2019.
