Inclusion criteria

Inclusion criteria: (1) One eye of a patient who underwent lens reconstruction by lens emulsification and aspiration between September 2017 and September 2020 (2) Patients who were able to implant and fix SN60WF (Alcon) in the lens capsule (3) Patients with best corrected visual acuity of 0.8 or more 1 to 3 months after surgery (4) Patients with data on examination / observation items (5) Patients with preoperative axial length of 22 mm or less or 26 mm or more

Exclusion criteria

Exclusion criteria: (1) Patients who underwent other eye surgery within 3 months after cataract surgery (2) Patients with uncontrolled glaucoma, progressive diabetic retinopathy, uveitis, retinal detachment, iris angiogenesis, corneal degeneration, history of eye surgery including corneal transplantation and corneal refractive surgery, and severe dry eye (3) Corneal astigmatism is 2.0D or higher (4) Patients with diseases that may affect eyesight, or patients who have used drugs that may affect eyesight (5) Patients with Zinn's zonule rupture, posterior capsule breakage, vitreous prolapse, hyphema, and IOL haptics that could not be completely fixed in the lens capsule during surgery (6) Patients who the doctor deems inappropriate because of systemic or ophthalmic diseases.

Design outcomes

Primary

Measure	Time frame
Predicted refraction error (difference between predicted refraction value and equivalent spherical value 1 to 3 months after surgery) calculated by SRK / T, Haigis and Barret Universal II for long axis (26 mm or more) and short axis (22 mm or less)	—

Secondary

Measure	Time frame
1. Best corrected vision 2. Biometric values (axial length, corneal refractive power, corneal thickness, anterior chamber depth, corneal lateral diameter)	—
