Rigid Gas Permeable Contact Lens Fitting For Visual Rehabilitation In Aphakia Following Trauma

Purpose:To study the feasibility, efficiency and safety of rigid gas permeable contact lens (RGPCL) fitting for visual rehabilitation in patients following ocular trauma. Methods:A retrospective study was performed on 17 unilateral aphakia of 17 patients (16 males and 1 female) after ocular trauma. RGP contact lenses (including 9 brown lenses) were fitted unilaterally for the visual rehabilitation in these 17 patients. The uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA) and best contact lens corrected visual acuity (BCLCVA) were recorded. Results: Seventeen eyes of 17 unilaterally aphakic patients were fitted with RGP contact lenses for visual rehabilitation, including 8 common lenses,9 brown lenses. The best corrected visual acuity (BCVA)= 0.3 was seen in 7 eyes (41.2%) with spectacle correction and 15 eyes (88.2%) with contact lens correction. The BCVA≧0.5 were 4 eyes (23.5%) and 10 eyes (58.8%), respectively.16 eyes (94.1%) wore RGP more than 8 hours every day, and one patient chose secondary posterior chamber intraocular lens (PC-IOL) implantation.7 eyes (41.2%) had corneal punctate staining,4 eyes (23.5%) complicated giant papillary conjunctivitis, in 2 eyes (11.8%) pre-existent corneal neovascularization not changed arfter RGP wearing. Conclusions:RGP contact lens is one of the selectable methods for treating refractive abnormalities in the traumatic unilateral aphakia. It is effective, safe, and tolerable. RGP contact lens has the potential to correct irregular corneal astigmatism. The brown RGP contact lens can improve photophobia and cosmetic appearance.
