Background:
Piggyback lens implantation is an alternative to exchange of the original intraocular lens (IOL) to treat high anisometropia in pseudophakic eyes. We present our results.
Patients And Method:
A second IOL (piggyback) was implanted in 27 patients from 2000 to 2006. Nineteen patients were clinically investigated late postoperatively, and data for the other eight patients were evaluated from the patients' files.
Results:
The patients were 65+/-9 years old. Follow-up time was 38+/-25 months. The mean preoperative spherical equivalent (SE) in the myopic eyes was -7.86+/-3.82 D and in the hyperopic eyes was 1.64+/-0.74 D. After surgery, the mean SE in the myopic eyes was -1.77+/-1.82 D and in the hyperopic eyes was -0.09+/-0.51 D. Postoperative anisometropia was reduced from 4.64+/-3.3 D. to 0.9+/-0.82 D.
Conclusion:
Piggyback lens implantation is a safe and effective surgical procedure and is less traumatic than exchange of the original IOL.
