Abstract
Purpose: :
To evaluate the accuracy of real-time intraoperative wavefront aberrometry in IOL power selection in eyes undergoing cataract surgery following previous refractive surgery.
Methods: :
Eyes must have undergone previous uncomplicated LASIK or PRK, have a well-centered topographic ablation profile, and require cataract surgery for age-related cataracts. A retrospective chart review was performed in which charts were reviewed of twenty patients who underwent phacoemulsification with IOL implantation with an intraoperative wavefront measurement to confirm if the visual target was achieved. Preoperative parameters measured were BCVA, UCVA, cornea curvature, axial length, and manifest refraction. Postoperative parameters include manifest refraction, BCVA and UCVA.
Results: :
In fifteen eyes, the intraoperative measurement confirmed that the IOL power was accurate, while in five eyes, the measurement indicated the need to exchange the IOL.
Conclusions: :
Intraoperative wavefront aberrometry enables real-time, intraoperative refractive measurements and improves refractive outcomes after cataract surgery with a previous history of corneal refractive surgery.
