Abstract Details

Purpose:

Estimation of the postoperative IOL position and the estimated anterior chamber depth (ACD) is still the main source of error in IOL power calculation. Haptic design and IOL material can 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 new 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 are included in this study. In each patient the AcrySof IQ IOL is implanted in one eye and the Clareon IOL in the contralateral eye according to randomisation. Study examinations are performed preoperatively, 1 hour, 1 week and 6 months after cataract surgeries. Slit lamp examination and ACD measurements using the IOL-Master 700 and AC-Master are carried out at each visit. Autorefraction, uncorrected distance visual acuity (UCDVA) and best-corrected distance visual acuity (BCDVA) are performed pre-operatively and 6 months post-operatively.

Results:

So far 48 eyes of 24 patients have been included. Recruitment is still ongoing. In total 100 eyes of 50 patients will be included in the study. First results will be presented at the ESCRS in Marrakech.

Conclusions:

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