Clinical experience with adjustable scleral lenses

Area of Science:

• Ophthalmology
• Optometry
• Biomedical Engineering

Background:

• Scleral contact lenses are crucial for managing complex visual impairments.
• The fitting process for scleral lenses can be challenging, requiring precise parameter adjustments.

Purpose of the Study:

• To evaluate the fitting process of adjustable scleral lenses (Zenlens).
• To determine the frequency and indications for parameter adjustments in scleral lens fitting.
• To assess the impact of adjustments on fitting success and patient outcomes.

Main Methods:

• Prospective analysis of scleral lens fittings in a private clinic.
• Inclusion of patients with indications for scleral lens use (Zenlens).
• Analysis of 80 eyes across 45 patients with conditions like keratoconus, post-refractive surgery ectasia, and dry eye.

Main Results:

• Parameter modifications were necessary in 82.5% of the 80 eyes studied.
• Common reasons for adjustments included apical touch, sagittal height issues, and edge compression.
• Diagnoses included keratoconus (72%), radial keratotomy (12%), and dry eye (5%).

Conclusions:

• Adjustable scleral lenses (Zenlens) offer a promising approach for visual rehabilitation.
• The ability to customize lens parameters enhances fitting success and patient wearability.
• These lenses represent a valuable option for visual rehabilitation in patients needing scleral lens correction.
