Abstract
Introduction & Aim: Children after traumatic corneal lacerations, suffering from irregular corneal astigmatism, spectacle best-corrected (SVA) of less than 20/20 and unilateral amblyopia in children with BCVA less than 20/40. The purpose of this study was an objective evaluation of the clinical value of Rigid Gas Permeable Contact Lenses (RGPCLs) by investigating the cornea profile, optical defects and the simulated vision functions by using the Sirius topographer.
Methodology & Theoretical Orientation: A comparative study of visual acuity correction and improvement of visual disorders as corneal aberrations as (HOAs, LOAs, PSF and with and without RGPCLs fitting in 15 children with history corneal scars after trauma or irregular corneal incision after cataract extraction operation. We compared the UCVA, Spectacle (VA) and the BCVA post while fitting RGPCLs. We used the Sirius topographer (CSO) for evaluation of aberrometric corneal analysis preand while fitting RGPCLs.
Findings: Our study included fifteen children were fitting RGPCLs for 6 months under specific study wear regimen. Their age range was from 5-9 years with mean 7.2±1.1 SD. There was a significant improvement in the best corrected visual acuity and keratometric astigmatism while wearing RGPLCs (P=0.001). There was also a significant improvement in corneal aberrations
as; HOAs (P=0.008), LOAs, RMS & PSF (P=0.001).
Conclusion & Significance: The optical performance of RGP contact lens has been demonstrated to be an effective tool of visual rehabilitation in children with traumatic corneal lacerations. The corneal topography was an objective tool for detecting the optical disorders other than subjective tests of visual acuity assessment.
