Contact Lenses for Aphakia

Key Points

The aim is to identify key factors for fitting corneal lenses to aphakic eyes effectively.
Analyzed personal fitting experiences over five years with more than 1,400 aphakic eyes.
Employed a diagnostic trial set of eight lenses to determine optimal fitting dimensions.
Assessed the importance of lens thickness and edge treatment for comfort and usability.
Identified a critical center thickness of 0.35 mm or less for optimal lens fitting.
Established the need for special edge treatment to facilitate lens self-removal.
Achieved results showing extreme comfort and minimal spectacle blur for aphakic patients.

Abstract

ABSTRACT Many important factors governing the design and fitting of tiny‐thinner single‐cut corneal lenses for aphakics are derived and presented here from a five‐year personal experience of fitting more than 1,400 aphakic eyes with lenses of this exact type. A center thickness of 0.35 mm or less seems to be the critical factor in fitting of tiny‐thinner single‐cuts for aphakics. Exact dimensions are presented here of an eight‐lens diagnostic trial set which is essential for determining a fit with “maximal bearing surface.” Special edge treatment is essential to aid “self‐removal” which is the number one problem with these lenses. “Extreme comfort,” minimal “spectacle blur” and no “limbal encroachment” pathology, are good reason for fitting these tiny‐thinner single‐cuts for aphakics.
