Comparison of PRESBYOND Laser Blended Vision and Conventional Monovision LASIK in Individuals With Presbyopia: A Randomized Clinical Study

The goal of this clinical trial is to learn if laser blended vision (LBV) works better than traditional monovision LASIK to correct presbyopia in adults aged 40 to 55 years. Presbyopia is an age-related condition that makes it hard to see things up close. The study will also evaluate the safety of both procedures. The main questions it aims to answer are: Does LBV improve distance, intermediate, and near vision at the same time after surgery? Is LBV as safe as traditional monovision LASIK? Researchers will compare laser blended vision to traditional monovision LASIK to see if LBV provides better overall vision after surgery. Participants will: Be randomly assigned to receive either laser blended vision or traditional monovision LASIK Have standard eye examinations before surgery Undergo LASIK surgery using the assigned method Return for follow-up visits at 1 week, 1 month, 3 months, and 6 months after surgery Complete vision tests and questionnaires about visual quality and satisfaction

An Evaluation of Myopia Control Lenses on Wearing Experience in Myopic Children

The goal of this research study is to understand the wearing experience of A.M.L. series of lenses in myopic children. The main questions it aims to answer are: * How quickly and effectively children adapt to the A.M.L. series of lenses? * The proportion of children who adapted to the A.M.L. series of lenses within 4 to 6 days? 40 myopic children aged 6 to 12 years will be recruited as participants, and all of them will be wearing A.M.L. series of lenses. Participants will: * Wear A.M.L. series of lenses for a period of 2 weeks * Visit at day 4-6, week 1 and week 2.

Post Marketing Clinical Study on the Efficacy of Lenses From a New Prescription Protocol

The goal of this clinical trial is to assess improvements in visual performance and patient outcomes in wearing new spectacle lenses in general population. The two spectacle lenses will be compared after two weeks of wearing. The aims are: * to evaluate the visual superiority, and quality-of-life implications of Essilor® AVA™ spectacle lenses prescribed after a new subjective refraction protocol named AVA™ protocol. * to understand the benefits of using a high accuracy instrument and testing sequence over the standard testing sequence in determining a glasses prescription, as well as the overall subjective performance of the resulting glasses.
