Clinical application of rigid gas permeable contact lens in 5 infants and toddlers after cataract surgery

Abstract

Objective To investigate the safety, effectiveness and fitting method of rigid gas permeable (RGP) contact lens after cataract surgery in infants and toddlers. Methods A retrospective analysis was performed on 6 eyes of 5 cataract children who visited our Aier Eye Hospital from November 2019 to December 2021. All patients were treated with RGP contact lens after cataract extraction and followed up for 6 months. RGP loss and replacement cycle, as well as changes in nystagmus and visual acuity were observed and evaluated to summarize the experience and analyze the safety and efficacy of lens therapy. Results All patients were healthy in ocular surface condition. One case abandoned to wear the lens. The period of lenses loss and replacement was 2.4~5.4 months per piece; The dropout frequency was 1~3 times per year; Displacement frequency was 3~4 times per day; Nystagmus was observed at 0~23 times per minute before wearing the lenses, and disappeared in the later follow-up period; The vision acuity was 0.5 (case 1 with lenses, optomotor nystagmus) and 0.2~0.67 (at 24 weeks after wearing lenses, self-made short-distance vision test card), respectively. Conclusion RGP contact lens are safe and effective for improving visual function in infants and toddlers after cataract surgery, which can be further popularized. Improving fitting techniques, optimizing examination methods, and strengthening follow-up education can improve the clinical therapeutic effectiveness of RGP and reduce costs in clinical practice.
