Early pigment dispersion and raised intraocular pressure after uneventful central-hole implantable collamer lens surgery

Abstract

Introduction: With ever-increasing cases of myopia worldwide, there has been a quantum jump in the number of refractive procedures. 3 cases who had an uncomplicated implantable collamer lens (ICL) surgery in both eyes, but had a new complication, are presented here. This is not yet described in the literature to the authors' knowledge. Patient and Clinical Findings: 2 weeks after uneventful bilateral ICL surgery, the patients presented with slight blurring of vision in 1 eye only. On examination, there was excessive pigment dispersion in the anterior chamber both in front of and behind the ICL. They also had raised intraocular pressure (IOP) a few days later, possibly due to blockage of the trabecular meshwork by iris pigments. Diagnosis, Intervention, and Outcomes: All the patients were managed conservatively on anti-inflammatory and IOP-lowering eyedrops. The dispersed pigments decreased with normalization of IOP after 2 to 4 weeks of conservative management with no blurring of vision. However, the pupil remained slightly dilated and irregular in all these cases. Conclusions: The excessive pigment dispersion seen after ICL surgery is not commonly encountered after ICL surgery and can be managed conservatively.
