Condition: High Myopia · Cataract · Sponsor: Jin Yang
Study Purpose: This prospective, self-controlled clinical study aims to evaluate the impact of capsular tension rings (CTR) on intraocular lens (IOL) stability in high myopia patients undergoing bilateral cataract surgery. Each patient will receive CTR implantation in one eye, with the fellow eye serving as control. Postoperative outcomes, including visual acuity, refraction, IOL positioning, and visual quality, will be compared between eyes to assess the effectiveness of CTR. Study Methods: Eligible participants (axial length ≥ 26.0 mm) will undergo femtosecond-assisted phacoemulsification with identical IOLs implanted in both eyes. One eye will be randomly assigned to receive a CTR. All surgeries will be performed by the same surgeon. Follow-up will be conducted at 1 day, 1 week, 1 month, 3 months, and 6 months postoperatively. Assessments will include UCVA, BCVA, refractive error, anterior segment OCT, IOL decentration and tilt, and visual quality (iTrace). Sample Size and Population: A total of 60 patients (120 eyes) will be enrolled. Inclusion criteria include age ≥ 18 years and bilateral cataracts with high myopia. Exclusion criteria include other ocular diseases, history of severe ocular trauma, or poor visual potential. Patients will be stratified by axial length into three groups: ≤28 mm, 28-30 mm, and \>30 mm. Study Procedure: After informed consent and baseline examinations (including ocular biometry and imaging), patients will undergo surgery and be followe…
