Abstract Details

Purpose:

Estimation of the postoperative anterior chamber depth (ACD) is still the main source of error in IOL power calculation. Haptic design and IOL material have an influence on the ACD. Our aim is to investigate the postoperative ACD variability between the hydrophobic AcrySof IQ IOL (Alcon) and the Clareon IOL (Alcon) made of a novel modified hydrophobic acrylic material.

Setting:

Vienna Institute for Research in Ocular Surgery (VIROS), a Karl-Landsteiner-Institute, Hanusch Hospital, Vienna

Methods:

Patients scheduled for bilateral cataract surgery without any ophthalmic abnormality that could compromise visual function or the measurements were included in this study. In each patient the AcrySof IQ IOL was implanted in one eye and the Clareon IOL in the contralateral eye according to randomisation. Study examinations were performed preoperatively, 1 hour, 1 week and 6 months after cataract surgery. Slit lamp examination and ACD measurements using the IOL-Master 700 and AC-Master were carried out at each visit. Autorefraction, uncorrected distance visual acuity (UCDVA) and best-corrected distance visual acuity (BCDVA) were tested preoperatively and 6 months postoperatively.

Results:

All patients have been included, in total 100 eyes of 50 patients. Follow-up visits will be completed in August 2020. Therefore final results will be presented at the ESCRS in Amsterdam.

Conclusions:

We will analyse whether the new modified Clareon IOL is not inferior to the AcrySof IQ IOL in postoperative anterior chamber depth variability. The final conclusions of the study will be presented at the meeting.
