In this retrospective case series, investigators reported on how mild to moderate myopes fared in the long term with small incision lenticule extraction (SMILE). Investigators reviewed the medical records of the 34 patients included in the study. The mean preoperative spherical equivalent of the 54 eyes was –4.11. At the 5-year postoperative mark, 93% of patients were within 0.5 D of intended correction, and all were within 1 D. None of the patients experienced any loss of corrected distance visual acuity lines or any vision-threatening complications. Investigators concluded that with SMILE there was predictable correction of spherical equivalent refractive error, and results were stable at the long-term follow-up.

Effect of a patient information video on the preoperative anxiety levels of cataract surgery patients

Can viewing an informative video ease patient concerns about undergoing cataract surgery? Investigators examined this in a prospective controlled trial involving 200 patients. Half of the patients, who had not seen an informative video on cataract surgery, were asked to fill out a questionnaire based on the Amsterdam Pre-operative Anxiety and Information Score and were given an 80 mm visual analogue score (VAS) for anxiety. Those who had watched the video also filled this out. Investigators found that those who watched the video had a lower VAS at 11.2 mm versus 45.5 mm for those who had not. When shown the statement “I am worried about the procedure,” those who watched the video were found to be in the “Not at all worried range,” while those in the control group were in the middle between extreme concern and no concern at all. Investigators concluded that a patient information video seen preoperatively was an effective and low-cost measure for reducing anxiety before cataract surgery, which might improve a patient’s overall experience with the procedure.

Trabecular microbypass stent implantation in pseudophakic eyes with open angle glaucoma: long-term results

This retrospective, consecutive case series examined how those with mild to moderate open angle glaucoma fared with use of the trabecular microbypass stent as their only procedure. Investigators found that at the 48-month postoperative mark, mean IOP was reduced 23% from 20.33 mm Hg to 15.65 mm Hg. The mean number of glaucoma medications fell from 2.08 prior to surgery to 1.46 at the 48-month postoperative mark. In cases where IOP was 18 mm Hg or higher, implantation of the microbypass stent resulted in a statistically significant reduction in the number of medications used as well as in the level of IOP. Following surgery 6% of eyes experienced pressure spikes of 15 mm Hg or greater, however, there were no intraoperative or postoperative complications. Also, a secondary glaucoma surgery was required in 20% of eyes. The conclusion reached was that use of a single microbypass stent was effective for providing IOP reduction over a sustained period. Those eyes with higher baseline IOP experienced the greatest pressure reduction.
