Visual Outcomes of an Enhanced Monofocal Intraocular Lens Targeted for Monovision in Highly Myopic Eyes: a Randomized Controlled Trial

The goal of this clinical trial is to evaluate whether an enhanced monofocal intraocular lens targeted for monovision can improve visual outcomes in patients with cataract and high myopia (axial length ≥ 26 mm). The main questions it aims to answer are: For people with cataract and high myopia, does an enhanced monofocal intraocular lens targeted for monovision provide greater binocular uncorrected distance visual acuity compared with targeting myopia in both eyes? Does an enhanced monofocal intraocular lens targeted for monovision provide comparable binocular uncorrected intermediate and near visual acuity, contrast sensitivity, reading ability, spectacle independence, stereopsis, and photic phenomena compared with targeting myopia in both eyes? Researchers will compare an enhanced monofocal intraocular lens targeted for monovision with one targeted for myopia in both eyes to determine whether the monovision strategy is more effective. Participants will: Undergo phacoemulsification with enhanced monofocal intraocular lens implantation. Attend follow-up visits at 1, 3, 6, and 12 months after cataract surgery.
