Filter by:This research study aims to compare whether Phenylephrine 2.5% ophthalmic eye drop solution can serve as a better indicator of the effect of a drooping upper eyelid (ptosis) by covering part of the upper portion of the field of vision as compared to traditional use of tape to lift up the upper eyelid in the evaluation of patients for surgical upper eyelid repair.
The goal of this prospective observational study is to learn about the impact of conventional eyelid correction surgery on the eye's health and function in ptosis and eyelid retraction patient. The main questions it aims to answer are: • 1. Changes in corneal topography, higher-order corneal aberrations, corneal biomechanical characteristics, and corneal epithelial thickness before and after the surgery 2. Influence of corneal refraction examinations , vision change, and tear film function after the surgery Fifty participants will undergo conventional eyelid correction surgery by the same ophthalmologist (YH Wei) and non-invasive examinations before and after the surgery. The patient will be separate to 2 groups, including 30 with correction for ptosis and 20 with correction for eyelid retraction. The research will collect information of the operated eye and fellow eye, and the data will be compared between operated and fellow eye and with the other group.
The purpose of this study is to observe and report the effects of topical ophthalmic brimonidine in oculofacial plastic surgery.
This study seeks to determine if bupivacaine injection of eye muscles can make them stronger and stiffer, and thereby correct the position of eyes that are turned in or mis-aligned, a condition generally termed strabismus. It seeks further to find out the different effects of various concentrations or formulations of bupivacaine, and whether addition of Botox to other eye muscles can add to the effect of bupivacaine and enhance the correction of strabismus.
