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 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 will be included. In each patient the AcrySof IOL will be implanted in one eye and the Clareon IOL in the contralateral eye according to randomisation. Study examinations will be performed preoperatively, 1 hour, 1 week and 6 months after cataract surgeries. Slit lamp examination, autorefraction, uncorrected distance visual acuity (UCDVA), best corrected distance visual acuity (BCDVA) and ACD measurements using IOL-Master 700 and AC-Master will be carried out at each visit.

Results:

100 eyes of 50 patients will be included. Recruitment is still ongoing and therefore results are not available yet. First results will be presented at the ESCRS in Paris.

Conclusions:

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