Objective:

To evaluate the role and effectiveness of fenestrated scleral lenses in modern contact lens practice, particularly in managing corneal edema.

Key Findings:

• Fenestrated lenses may reduce corneal edema in compromised corneas.
• No significant difference in edema was found in healthy corneas between fenestrated and non-fenestrated lenses.
• Fenestrations may alleviate lens suction and midday fogging.
• There is a lack of consensus on the effect of fenestrations on intraocular pressure (IOP).

Interpretation:

Fenestrated scleral lenses are not commonly used but may provide benefits in specific cases, particularly for patients with corneal issues, highlighting the need for further research.

Limitations:

• Lack of consensus on the effect of fenestrations on IOP, with anecdotal evidence suggesting varying outcomes.
• Need for larger studies to confirm anecdotal evidence regarding edema management.

Conclusion:

Fenestrated scleral lenses may be beneficial in certain clinical scenarios, but further research is needed to establish their efficacy and safety, particularly regarding IOP changes.
