Posterior chamber silicone phakic intraocular lens

Area of Science:

• Ophthalmology
• Biomedical Engineering

Background:

• Investigated the efficacy, safety, and stability of silicone posterior chamber intraocular lenses for high myopia correction in phakic eyes.
• Addressed the need for effective solutions for high myopia, a condition affecting numerous individuals worldwide.

Purpose of the Study:

• To evaluate the refractive correction, visual acuity outcomes, and complication rates associated with silicone posterior chamber intraocular lens implantation for high myopia.
• To assess the long-term stability and patient satisfaction following the procedure.

Main Methods:

• A silicone posterior chamber plate-style intraocular lens was implanted in 38 consecutive phakic eyes with high myopia (ranging from -7.00 to -28.00 diopters).
• Follow-up ranged from 3 to 24 months, with regular assessments of refractive error and visual acuity.

Main Results:

• Refractive correction within +/- 1.00 D was achieved in 71% of eyes by 3 months post-surgery and remained stable.
• Spectacle-corrected visual acuity improved by at least two lines in 63% of patients, with no loss of vision.
• High patient satisfaction (92%) was reported, with complications primarily linked to surgical technique, not lens biocompatibility.

Conclusions:

• Silicone posterior chamber plate-style intraocular lenses offer a predictable, safe, and stable method for correcting high myopia.
• The procedure demonstrated favorable visual outcomes and high patient satisfaction, with a low complication rate.
• This lens represents a viable option for managing high myopia in phakic individuals.
