Objective To observe the position of posterior chamber phakic intraocular lens and its relationship to the iris and the crystalline in vivo through UBM. Methods There were 33 eyes with high myopia who accepted surgery treatment All surgeries were performed using topical anesthesia and clear corneal incision. The posterior chamber phakic intraocular lens manufactured with STAAR collamer was implanted between transparent lens and iris. During the course of the surgery, iridectomy was done at one clock. Each eye was examined carefully before and after surgery. The position of ICL was observed at 1, 3 and 6 months. Result All eyes of preoperative uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA)were 0.04± 0.06, 0.5± 0.3 respectively and postoperative were 0.5± 0.2, 0.8± 0.2 respectively. At sixth month of postoperative the anterior chamber depth was 2802± 297 m and ICL central vault was 329 m. UBM verified the contact between ICL and iris. Both haptics were supported by zonula in 22 eyes; one haptic was supported by zonula and other haptic by ciliary body in 7 eyes; Both haptics were supported by ciliary body in 4eyes. The extreme tip of two haptic was at sulcus in 20 eyes. In 6 eyes, rotation of the lens was observed. Conelusions Thephakic IOLs are a safety and effective treatment for the correction of high myopia. It is important that looking for a new and accurate method to measure sulcus diameter in order to reduce complication resulted by inaccurate ICL vault.
