Ultrasound biomicroscopy (UBM) [Figure 1] revealed the presence of ring iridociliary cyst in the left eye and a partial one (2 o'clock hours temporally) in the right eye.

Aurolabs, India) was injected into the sulcus, under the iris, creating space for the endoscope. A 20-gauge curved endoscopic probe (Endo Optiks, Little Silver, NJ, USA), coupled with an 810 nm diode laser (IRIS Oculight SLx, Iris Medical Inc., Mountain View, CA, USA), was introduced into the eye through the clear corneal phaco wound, advanced posterior to the pupil and into the sulcus, and the ciliary processes and the cyst were visualized [Figure 2].

In ECPL, typically, the tail of the ciliary processes [Figure 3] are targeted with the laser, to shrink them posteriorly, away from the iris. Individual ciliary processes were targeted, and endpoint of the laser treatment was determined by adequate whitening and shrinkage of the tail of the ciliary process, away from the cyst [Figure 3], avoiding iatrogenic rupture of the cyst.
