BACKGROUND: We investigated the efficacy, safety, and stability of correction achieved with a silicone posterior chamber intraocular lens used to correct high myopia in phakic eyes.
PATIENTS AND METHODS: A silicone posterior chamber plate-style intraocular lens (Chiron, Adatomed) was implanted in 38 consecutive phakic eyes with high myopia (-7.00 to -28.00 diopters (D) over a period of 21 months. Follow-up ranged from 3 to 24 months.
RESULTS: Three months after surgery, refractions in 27 eyes (71%) ranged from -1.00 to +1.00 D and remained stable thereafter. Spectacle-corrected visual acuity improved at least two lines in 24 eyes (63%), and none was lost in any eye. Patient satisfaction was high (92%). The few complications that occurred were mostly related to imperfections in the surgical technique rather than lack of biocompatibility of the lens. No cataract or other vision-threatening complication was present at the end of the study.
CONCLUSION: This silicone posterior chamber plate-style intraocular lens provides a reasonably predictable, safe, and stable means of correcting high myopia.
