Evaluate Capsular Apposition to Intraocular Lens
In this study, the investigators examined the capsule-IOL interaction including anterior and posterior capsule adhesion, contact between posterior capsule and the posterior edge of intraocular lense (IOL), configuration of capsular bend and the incidence of posterior capsular opacity (PCO) between high myopia eyes and emmetropia eyes.

|Official Title:||Phase 1 Evaluate Capsular Apposition to Intraocular Lens in Subjects With High Myopia by Ultra-long Scan Depth Optical Coherence Tomography|

high myopia (axial length>26mm)
emmetropia (22<axial length<25mm) as control group.
Forty eyes of 40 cataract patients scheduled for phacoemulsification surgery were recruited, of which 20 eyes were high myopia (AL > 26mm) and 20 eyes were emmetropia (22 < AL < 25mm) as control group.
Methods: All eyes were examined by custom-built UL-OCT at 4 hours, 1 day, 7 days, 14 days, and 28 days after surgery.
Main Outcome Measures: Contact of the anterior and posterior lens capsule with the IOL optic surface was evaluated. Types of capsular bend were described at the last follow-up. The incidence of posterior capsular opacity (PCO) was evaluated.
