Aberrometry Changes and IOL Decentration
Narrative Responses:
Purpose
To study the aberrometric changes in the eyes with posterior IOL decentration.
Methods
All ophthalmic investigations were performed including Hartmann-Shack WASCA and CRS-Master aberrometry system. Ocular wavefront aberrations were measured in 24 eyes with IOL decentration (main group) and 52 eyes with a normal intracapsular position of IOL and 22 emmetropic (control groups).
Results
We revealed total aberrations and HOAs (especially trefoil, spherical-like and mild positive vertical coma) increasing in eyes with IOL decentration. However, the accuracy of IOL decentration aberrometry depends on the lens capsular opacification, secondary cataract and the level of IOL decentration.
Conclusion
All aberrations and especially high order aberrations (HOAs) are increased in the eyes with IOL decentration.
