To evaluate the characteristics of and risk factors for intraocular lens (IOL) pupillary capture in congenital ectopia lentis(CEL).
In this retrospective case series, the surgical database of a referral center was searched for cases of CEL between 2014 and 2016. Characteristics of patients and eyes were collected and the main included variables were age of onset, dislocation grade, axial length, sphere, cylinder, corneal astigmatism, ocular complications, surgical technique to correct dislocation, duration of surgery, IOL type, preoperative and postoperative refractive error and corrected distance visual acuity (CDVA), interval between surgery and IOL pupillary capture occurred.
A total of 89 CEL patients were consecutively included, including 39(43.8%) CEL with IOL pupillary capture and 50(56.2%) CEL without IOL pupillary capture. The mean age was 53.661.6 months, with 58.4% being male and 48.3% being right eye. IOL pupillary capture occurred in 53.5% of moderate dislocation patients (in which the lens edge uncovers 25–50% of the dilated pupil) and 77.8% of severe dislocation patients (in which the lens edge uncovers greater than 50% of the pupil). The axial length of patients with and without IOL pupillary capture were 25.5±2.49 and 24.6±2.39, respectively. IOL pupillary capture occurred in 69.2% of patients with strabismus, in 7.69% of patients who implanted 1-poece acrylic IOL and in 50% of patients who implanted 3-poece acrylic IOL. Risk factors for pupillary capture in CEL was patients complicated with strabismus (OR=13.5, P=0.005).
IOL pupillary capture in CEL remains a common complication following surgery for ectopia lentis and strabismus is a risk factor for pupillary capture. Caution should be taken in CEL patients with strabismus when planning the surgery.
