Clinical Report: Visual Rehabilitation Following Keratoplasty

Overview

This report evaluates the role of contact lenses in visual rehabilitation after keratoplasty, highlighting significant improvements in visual acuity and comfort. Despite some complications, including corneal graft rejection and conjunctival hyperemia, scleral lenses are effective for enhancing vision post-surgery.

Background

Visual rehabilitation following keratoplasty is crucial for restoring patients' quality of life. Contact lenses, particularly scleral lenses, have emerged as a primary option for correcting vision in post-keratoplasty patients. Understanding the outcomes and complications associated with contact lens use in this population is essential for optimizing patient care.

Data Highlights

Key Findings

• All studies reported significant improvement in visual acuity with contact lens correction.
• Most patients could wear lenses comfortably for 8 to 12 hours daily.
• Contact lens dropout rates varied from 0% to 39%, mainly due to intolerance or discomfort.
• Common complications included corneal graft rejection, conjunctival hyperemia, corneal epithelial trauma, graft edema, and microbial keratitis.
• Careful monitoring is essential to minimize the risk of graft rejection, especially in high-risk patients.

Clinical Implications

Clinicians should prioritize fitting scleral lenses for post-keratoplasty patients to enhance visual outcomes. Regular monitoring and patient education on recognizing signs of graft rejection and urgent symptoms are critical for managing potential complications effectively.

Conclusion

Scleral lenses represent a valuable tool in visual rehabilitation following keratoplasty, with careful management necessary to mitigate risks associated with graft rejection and other complications. Lifelong monitoring is essential.
