# Scleral lens fitting for keratoconus

Scleral lenses are large, custom-made contact lenses that rest on the white of the eye, vaulting over a steep or irregular cornea. They can give clearer, more comfortable vision for many people with keratoconus.

## How fitting works

The fitting process is more detailed than with standard lenses. Several appointments are common while the shape is refined.

- Special scans measure corneal curvature and overall eye shape
- Trial lenses help judge comfort, vision, and fluid reservoir depth
- Your practitioner checks for adequate clearance and healthy tear exchange
- Fine-tuning may involve adjusting diameter, curvature, or edge design

## What to expect day to day

Most patients adapt well with practice and support. Good hygiene and regular reviews keep your eyes safe.

- Insertion uses a small bowl of preservative-free saline to fill the lens
- Removal techniques are taught using a suction plunger or fingertip
- Daily cleaning and occasional protein removal tablets protect the surface
- Report redness, pain, or reduced wear time promptly for assessment
