Rigid Gas Permeable Contact Lens as a Vision-Sparing Tool in Children After Traumatic Corneal Laceration
Insights
Rigid gas permeable contact lenses significantly improved vision and reduced corneal aberrations in children with traumatic corneal scars. This study highlights their clinical value for visual rehabilitation.
Area of Science:
- Ophthalmology
- Corneal disease
- Pediatric optometry
Background:
- Traumatic corneal scarring can impair vision in children.
- Visual rehabilitation is crucial for pediatric ocular trauma patients.
Purpose of the Study:
- To assess the clinical effectiveness of rigid gas permeable contact lenses for children with traumatic corneal scarring.
- Evaluate the impact of these lenses on visual acuity and corneal aberrations.
Main Methods:
- A comparative study involving 15 children (ages 5.7-14) with corneal scars and reduced visual acuity.
- Children wore spherical rigid gas permeable contact lenses for 6 months.
- Visual acuity and corneal aberrations were measured before and after lens wear using corneal topography.
Main Results:
- Significant improvement in best corrected visual acuity (BCVA) with rigid gas permeable contact lenses compared to spectacles (P = .001).
- Marked reduction in keratometric astigmatism (P = .001) and corneal aberrations, including higher-order aberrations (P = .008).
Conclusions:
- Rigid gas permeable contact lenses are effective for visual rehabilitation in children with traumatic corneal lacerations.
- Corneal topography serves as an objective method for identifying optical irregularities.
Purpose:
To evaluate the clinical value of rigid gas permeable contact lenses in children after traumatic corneal scarring.
Methods:
This comparative study included 15 children (age range: 5.7 to 14 years; mean ± standard deviation = 9.4 ± 2.9 years) with corneal scars and best corrected visual acuity (BCVA) of worse than 20/20, history of penetrating ocular trauma, and/or cataract extraction. All children were advised to wear spherical rigid gas permeable contact lenses for 6 months with a special regimen. Visual acuity was compared before and after fitting. The total and anterior surface aberrations of all children were measured using a corneal topographer before and after treatment.
Results:
There was a significant improvement in the BCVA after wearing rigid gas permeable contact lenses compared to spectacle visual acuity (P = .001). There was also significant improvement of the keratometric astigmatism (P = .001) and corneal aberrations such as higher order aberrations (P = .008), lower order aberrations, root mean square, and point spread function (P = .001).
Conclusions:
The optical performance of rigid gas permeable contact lenses has been demonstrated to be effective in the visual rehabilitation of children with traumatic corneal lacerations. Corneal topography was an objective tool for detecting optical disorders. [J Pediatr Ophthalmol Strabismus. 2018;55(3):178-181.].
