Complete resolution of hyperopic shift in anterior capsular contraction syndrome after Nd:YAG laser capsulotomy: a case report

Background: Anterior capsular contraction syndrome (ACCS) is a disorder in which the anterior capsulectomy opening shrinks excessively. One of the many factors that have been discovered to aggravate the problem is a lack of zonular support for the lens capsule. The prognosis for non-progression of contractions after Nd:YAG anterior capsulotomy is quite excellent. This study aims to present a complete resolution of the hyperopic shift in an anterior capsular contraction syndrome (ACCS), a rare complication of cataract surgery. Case Illustration: This case report presented a 63-year-old female who developed ACCS in the right eye two years after uncomplicated cataract surgery and intraocular lens implantation. A moderate hyperopic shift of +3.00 D was noted in the affected eye at the initial presentation. Slit-lamp examination revealed an anterior capsule opacification and anterior capsular contraction with fibrosis surrounding the capsulorhexis opening. Ocular and systemic past medical history was unremarkable, and no known risk factors associated with contraction syndrome were found. Nd:YAG laser capsulotomy with six relaxing incisions was performed to release the anterior capsular contraction. Two weeks following capsulotomy, the patient's visual acuity remarkably improved to LogMAR 0.00 without correction. The hyperopia was completely resolved, and a decrease in anterior chamber depth compared to pre-capsulotomy measurement was noted. ACCS is a possible complication following capsulorrhexis performed in uneventful cataract surgery, which may occur in patients with no known ocular or systemic risk factors. ACCS is commonly asymptomatic, and hyperopic shift is a rare manifestation of ACCS. The backward shift of the intraocular lens (IOL) induces hyperopia due to the anterior capsule contraction. The preferred treatment for ACCS is relaxing incisions using Nd:YAG laser capsulotomy. Conclusion: Hyperopic shift in ACCS is a rare complication of cataract surgery. However, prompt treatment of contraction release with Nd:YAG laser capsulotomy effectively restored visual function.
