When capturing a scleral image in the biometry occasionally an error message can appear as “not enough vessels near the limbus have been found”, in consequence, using the intraoperative toric axis assistant is not possible. Timolol 0.25% is a common and available non-selective beta-adrenergic blocker. The use of topical timolol 0.25% drops as an effective method to enhance preoperative limbal vessels reference image is discussed in this touchOPHTHALMOLOGY interview with Dr Eduardo Roditi (Westmead Hospital, Sydney, Australia) as well as the clinical implications of these findings, and what further study is needed.
The presentation entitled ‘Topical Timolol 0.25% to Enhance Preoperative Reference Vessels Image in Digitally Assisted Intraoperative Axis Alignment for Toric IOL’ was presented at the American Society of Cataract and Refractive Surgery, April 22-26, 2022
Dr Eduardo Roditi won the first prize in the ASCRS 2022 film awards in home production.

- Could you tell us about the case study you are reporting?
- What are the clinical implications of these findings, and what further study is needed?
