Abstract Details


To assess the results of lens replacement surgery in patients with congenital iris coloboma.


S.Fyodorov Eye Microsurgery Complex


11 patients (17 eyes) with cataracts of various densities underwent clear corneal phacoemulsification and IOL implantation. As a first step of pupil reconstruction iridoplasty with Siepser sliding knot sutures was done at the time of surgery. The 2nd second step was performed from 3 to 6 months after the initial surgery – for that purpose Argon laser applications in midperiphery of the iris were used to correct pupil size and position.


In 3 cases modified CTR was sutured to the sclera at 6 o’clock position. The most common intraoiperative complication was mild iris bleeding (6 eyes). No major complications were observed after the surgery. Preoperative BCVA (Snellen) 0.08 +/- 0.06 improved to 0.69 +/- 0.21. Mean follow-up period was 21 months. After the 2nd step improvement in BCVA was achieved (0.1+/_0.04) due to slight reduction of astigmatism resulting from better pupil alignment with the center of the cornea.


In patients with cataract and congenital iris coloboma, two-step approach consisting of phacoemulsification, in-the-bag IOL implantation iris coloboma suturing, followed by laser pupilloplasty provided favorable functional and cosmetic results.
