Background
Prism correction in contact lenses offers an alternative to traditional spectacles for individuals with binocular vision disorders. Scleral lenses, particularly those incorporating prism, have shown promise in managing conditions like diplopia and anisometropia. Source: Gelles et al., 2026.
Data Highlights
Study
Findings
Gelles et al., 2026
All patients achieved 20/20 vision and resolution of diplopia.
Lee et al., 2021
Treated decompensated esotropia with 8 PD BO prism.
Frogozo, 2016
Elimination of horizontal diplopia with 6 PD BO prism.
Lindsay & Crock, 2005
Correction of vertical heterophoria with bitoric GP lens.
Key Findings
Prism can be incorporated into contact lenses to correct small-angle deviations.
Source: Gelles et al., 2026.
Wavefront-guided optics improved visual quality and reduced higher-order aberrations.
Clinical Implications
Consideration of prism-incorporated scleral lenses for patients with binocular diplopia should be based on individual clinical assessments.
Conclusion
Further studies are warranted to explore the efficacy and limitations of prism-incorporated impression-based scleral lenses.
Before initiating any contact lens fitting, confirm retinal stability because many retinal diseases—including diabetic macular edema, retinal vein occlusion, and postoperative scarring following retinal detachment—can fluctuate over time.
