Coronavirus disease 2019 (COVID-19) is a multi-organ disease with a wide range of manifestations. Coagulopathy is one of the well-recognized complications of COVID-19. We report the case of a 42-year-old man who presented with progressively worsening low back pain of two days in duration. The pain was burning in character, non-radiating, and was not related to movement. The patient had a recent history of severe COVID-19 pneumonia requiring mechanical ventilation and has stayed in the intensive care unit for eight days. He was discharged three days before the acute onset of his back pain. Examination of the lumbar spine was unremarkable. However, lower limb examination revealed coldness and absent pulses bilaterally. The patient underwent computed tomography angiography which revealed complete occlusion of the lower abdominal aorta at its bifurcation. Emergency endovascular treatment was performed to aspirate the clot. The symptoms resolved following the procedure and the patient was discharged on the third post-intervention day. Saddle aortic embolism is a rare life-threatening condition that may present solely with low back pain. The case demonstrated a possible complication of COVID-19 that occurred after the recovery from the acute phase of the disease.

Diffuse lamellar keratitis (DLK) is not an uncommon complication of the small-incision lenticule extraction (SMILE) operation. Instrumental causes, such as contamination, are usually the underlying etiological route. Herein, we present an atypical case of DLK with numerous foci of cellular infiltrates on day 1. No evidence of any diffuse inflammatory response was reported. On the other hand, the multifocal response began to improve starting on the third day, after the administration of systemic steroids, with pain and discomfort significantly disappearing on the second day. Antibiotics were given as well, in the case of secondary infections. After 1 week of treatment and close monitoring, significant improvement was reported, and the slit-lamp examination was unremarkable.

This cohort study included 36 eyes of 21 patients with high myopia treated with angle supported phakic intraocular lens (pIOL). Endothelial cell density (ECD) at baseline, 6mo and 3y were 3017±296, 2775±265 and 2558±299 cells/mm respectively. ECD loss at 6mo was 7.2% and annual ECD loss was 3% over 36mo. Corrected distance visual acuity at 36mo was 0.4 logMAR or better in 32 (88.9%) eyes. Intraocular pressure did not change (=0.9). No eyes developed cataract, retinal detachment or pupillary distortion. Angle supported pIOL gives good visual outcome. Endothelial cell loss should be monitored.
