RESUMEN

PURPOSE: To evaluate long-term efficacy, safety, predictability and stability (refractive and keratometric) of myopic and myopic astigmatism correction with Small Incision Lenticule Extraction (SMILE). METHODS: Single center retrospective review of eyes undergoing SMILE from 2012-2015. Forty-two eyes (23 patients) with ≥ 5-year follow-up. Variables analyzed were preoperative, 3-month, 1-year and last follow-up uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction, spherical equivalent (SE) and mean keratometry. Descriptive statistics were performed and results reported following the Standard for Reporting Astigmatism Outcomes. RESULTS: Mean follow-up of 5.98 ± 0.90 years. Mean preoperative SE was -5.26 ± 1.22D (range -2.50 to -8.12D). Mean preoperative cylinder was -0.66 ± 0.61D (range 0.00 to -2.25D). Efficacy and safety indices were 0.86 and 0.98, respectively. In total, 81% of operated eyes achieved an UDVA of ≥ 0.09 logMar (20/25 Snellen). At the last follow-up, ≥1 line of CDVA was gained in 14% of eyes. Five percent lost 1 line of CDVA, and no eye loss ≥2 lines of CDVA. Sixty-nine percent of eyes were within ± 0.50D and 86% within ± 1.00D of the attempted SE correction. Ninety-one percent of eyes had ≤0.50D of postoperative astigmatism and 71% were within ± 15° from the intended correction axis. At the final follow-up, a statistically significant myopic regression of 0.19 ± 0.50D was observed (p = 0.01). CONCLUSIONS: Long-term results demonstrate that SMILE is effective, predictable and safe. SMILE has good stability, low regression compared to LASIK, and no signs of corneal ectasia staging within our standard criteria.

RESUMEN

PURPOSE: To evaluate long-term efficacy, safety, predictability, and stability of a posterior chamber phakic intraocular lens (Visian implantable collamer lens [ICL]) in eyes with ≥10 years of follow-up. SETTING: Instituto de Microcirugía Ocular, Barcelona, Spain. DESIGN: Retrospective study. METHODS: Eyes undergoing ICL implantation from 2008 to 2011 with ≥10 years of follow-up were included. Variables analyzed were preoperative, 1-month, 1-year, 5-year, and last follow-up uncorrected distance (UDVA) and corrected distance visual acuity (CDVA), manifest refraction, spherical equivalent (SE), endothelial cell count (ECC), and intraocular pressure (IOP). Descriptive statistics were performed and results reported following the Standard for Reporting Refractive Surgery Outcomes. RESULTS: 45 eyes (26 patients) were analyzed; the mean follow-up 11.35 ± 1.30 years. The mean preoperative SE was -10.06 ± 3.40 diopters (D) and the mean preoperative cylinder -1.55 ± 1.45 D. At the last follow-up, efficacy and safety indices were 0.79 and 1.12, respectively. In total, 32 eyes (71%) achieved an UDVA of ≥20/40. 22 eyes (49%) gained ≥1 line of CDVA, and 2 eyes (4%) lost ≥2 lines of CDVA. At the final follow-up, 19 eyes (42%) and 29 eyes (64%) were within ±0.50 D and ±1.00 D of attempted SE correction, respectively. 31 eyes (69%) had ≤1.00 D of postoperative astigmatism, and 29 eyes (74%) were within ±15 degrees from the intended correction axis. At the last visit, a statistically significant myopic progression of -0.75 ± 1.20 D was observed ( P = .01). ECC loss at the last follow-up was 9.85 ± 11.35%. IOP remained stable. There were no intraoperative complications. 3 eyes (7%) developed cataract after 10 years. CONCLUSIONS: The long-term results demonstrated that ICL was effective, predictable, stable, and safe.

RESUMEN

COVID-19 has posed an extraordinary burden on health and the economy worldwide. Patients with cardiovascular diseases are more likely to have severe illness due to COVID-19 and are at increased risk for complications and mortality. We performed a narrative literature review to assess the burden of COVID-19 and cardiovascular morbidity and mortality. Myocardial injury has been reported in 20%-30% of patients hospitalized due to COVID-19 and is associated with a worse prognosis and high mortality (~50%-60%). Proposed mechanisms of myocardial injury include inflammation within the myocardium (due to direct viral infection or cytokine storm), endotheliitis, coronary vasculitis, myocarditis, demand ischemia, plaque destabilization and right ventricular failure. The right ventricle is particularly vulnerable to injury and failure in COVID-19-infected patients, given the hypoxic pulmonary vasoconstriction, pulmonary microthrombi or pulmonary embolism. Echocardiography is an effective and accessible tool to evaluate left and right ventricular functions and risk stratify patients with COVID-19 infection. Cardiac MRI has detected and characterized myocardial injury, with changes compatible with other inflammatory cardiomyopathies. The long-term consequences of these inflammatory changes are unknown, but accumulating data will provide insight regarding the longitudinal impact of COVID-19 infection on cardiovascular morbidity and mortality.
