Telemedicine Follow-up for Routine, Low-Risk Oculoplastic Surgery

The investigators propose utilizing a simple telemedical protocol to allow patients to substitute the first post-operative visit with a remote survey that includes essential post-operative history, vision measurement, and photographs, all of which can be provided using a personal computer, tablet, or smart phone. The investigators have selected for this purpose a subset of oculoplastic procedures involving the eyelid and lacrimal system that have well-reported low rates of serious complications, since high-risk procedures will likely always require close, in-person care. The investigators hypothesize that telemedicine follow-up for the first post-operative week after low-risk oculoplastic surgery will decrease the time burden on patients without compromising their satisfaction or increase the risk of late post-operative complications.

The Diagnostic Accuracy of Advanced Imaging in Identifying Suspected Skin Cancer (Basal Cell Carcinoma) Around the Eyes

The purpose is to investigate the diagnostic value (sensitivity and specificity) of dermal-Optical Coherence Tomography (D-OCT, VivoSight Dx), in patients with clinically suspected BCC lesions inside the periocular region and compare these results to previous reports using D-OCT in diagnosing lesions outside the periocular area. The Hypotheses: * The sensitivity and specificity of D-OCT in diagnosing BCC inside the periocular region is comparable to previous reports on BCC lesions outside the periocular region when the standard D-OCT probe is used. * The sensitivity and specificity of D-OCT in diagnosing BCC inside the periocular region is increased when the customised D-OCT probe is used. * The sensitivity and specificity of D-OCT in diagnosing periocular BCC is comparable to punch biopsy when both standard and the customised D-OCT probes are used. * D-OCT with the 10 and 20-millimeter standoff is capable of subtyping periocular BCC. * The inter-observer variation in diagnosing and sub-typing periocular BCC decreases with increasing experience in the scanning procedure. * The number of scans to correctly interpret D-OCT decreases with increasing experience in the scanning procedure. * Delineation of periocular BCC tumour extension is possible using both D-OCT probes
