Purpose: This will be the thirteenth annual survey on the practice patterns of the Canadian Ophthalmological Society (COS) members in cataract surgery.
Study Design: Web based
Methods: This survey will be conducted in January 2021 when an e-mail with a link to Red Cap will be sent to all the COS members who have indicated that their practice focus is on Cataract and Intraocular lens (IOL) implant. Two reminder e-mails will be sent at 2 weeks interval.
Results: In 2020, most of the respondents (39%) waited 1 minute and 27.3% waited 2 minutes before draping for cataract surgery. The most popular lens formula was the Barrett Universal II (51.4%). The majority of the respondents used the same instrument to measure the K readings and the axis of astigmatism (59%). Most of them (75.6%) used the IOL Master to do so. 62.8% of the respondents corrected astigmatism at the time of cataract surgery. The majority (91.8%) used a Toric IOL to do so. Of these, 67.8% corrected 1 diopter or more of with the rule astigmatism while 80.9% corrected 1 diopter or less of against the rule astigmatism. 43.6% of the respondents aimed for monovision following cataract surgery. 55.8 % aimed for a difference of 1.25D and 1.75D between the two eyes. Presbyopia correcting lenses were used by 57.7% of the respondents. However, 80% did so for only 10% of the time. 77% of the respondents would see their patients on the first day following cataract surgery, while 22% would see them on the same day.
Conclusions: This annual survey has highlighted some trends in the practice patterns of the Canadian Ophthalmological Society members in cataract surgery and gives the membership valuable information as to how their peers are practising.
