Sunrise in the eye: Bilateral superonasal lens subluxation in Marfan syndrome.

To describe the case of a patient with Marfan syndrome who had bilateral superonasal lens subluxation. The case of a male patient, aged 18, who complained of having impaired vision in both eyes (BE) since he was a toddler, was presented. On examination of the patient, features suggestive of Marfan syndrome were revealed, as well as bilateral intraocular lens subluxation.

Extended depth of focus intraocular lens versus a new monofocal intraocular lens: A prospective comparative and interventional study.

Purpose: To compare the visual outcome findings between a new monofocal intraocular lens (IOL) (Tecnis Eyhance) and extended depth of focus (EDOF) IOL (Appasamy Supraphob Infocus).

Methods: This prospective comparative interventional study evaluated 31 patients after implantation of Tecnis Eyhance (15 patients) and Supraphob EDOF IOL (16 patients). The uncorrected and corrected distance and intermediate and near visual acuity were measured at postoperative day 1, 1 week, 4 week, and 3 months.

A study of post-operative clinico-imaging status and visual outcome after idiopathic macular hole surgery with amniotic membrane plug.

The aim of this study was to determine the efficacy of hAM plug in the treatment of idiopathic macular hole and to see its post-operative visual improvement and anatomical apposition. 10 eyes of 10 patients who had idiopathic MH underwent a pars plana vitrectomy (PPV) with the hAM plug implanted in MH. The patients were followed up on 2nd day, 1st week, 3rd week, 6th week and 3rd month.

Aeration characteristics of a rectangular stepped cascade system.

Aeration experiments, maintaining nappe flow conditions, were carried out on a rectangular stepped cascade of total height 3.0 m to determine the total number of steps, slope of the entire cascade and hydraulic loading rate at which maximum overall aeration efficiency occurs, keeping the surface area of individual steps constant. Based on dimensional analysis, the overall aeration efficiency at standard conditions (E(20)) was expressed as a function of square of total number of steps (N(2)) and dimensionless discharge (d(c)/h), where d(c) and h represent critical depth in a rectangular prismatic channel and individual step height respectively.
