“…Thus, by providing a more homogeneous postoperative ocular surface, it offers a better postoperative visual quality. [15] So, Zyoptix custom HD treatment is superior to Proscan conventional treatment in the correction of low and high order eye aberrations.…”

‫ـــــــــــــــــــــــــــــــــــــــــــــــــ‬ ‫ـــــــــــــــــــــ‬ ‫ــــــــــــــــــــــــــــــــــ‬ ‫ــــــ‬ ‫ــــــــــــ‬ Background: The eye, like any other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction and scatter. Aim of the Work: To compare between the effect of different types of LASIK (proscan ablation and Zyoptix HD ablation) in correction of higher order abberations. Patients and Methods: This comparative prospective study was conducted on 50 eyes of 27 Egyptian patients divided into two groups, Group A: Twenty five eyes of 14 patients (11 patients both eyes and 3 patients one eye) underwent conventional LASIK (Proscan) using mechanical microkeratome. The mechanical microkeratome (Moria) was used to create the flap (superior hinge). The selected plate thickness was 110 µm.And Group B: Twenty five eyes of 13 patients (12 patients both eyes and 1 patient one eye) underwent custom LASIK (Zyoptix HD) using mechanical microkeratome. The mechanical microkeratome (Moria) was used to create the flap (superior hinge).The selected plate thickness was 110 µm. Results:The results found in our study indicate that conventional LASIK surgery was associated with higher

“…Myopia often occurs between six and eight years of age, develops rapidly between 13 and 16 years of age, and stabilizes after 16 years of age [ 6 ]. Treatment of myopia in modern medicine is mainly optometric, and includes the use of spectacles (single-vision lenses (SVLs) and progressive addition lenses [ 7 ] and contact lenses [ 8 , 9 ]. Refractive surgeries include laser-assisted in situ keratectomy, photorefractive keratectomy [ 10 – 12 ], and posterior chamber phakic intraocular lenses [ 13 ].…”

BackgroundMyopia is a public health problem worldwide and its incidence increases with age. The use of acupuncture to treat myopia is a common practice in China, however, the use of acupuncture to treat myopia is disputed in other parts of the world. This study aims to determine the safety of acupuncture to treat myopia and its efficacy over six months.Methods/DesignA randomized, parallel, single-center, assessor- and statistician-blinded, controlled clinical trial will be performed. A total of 100 teenagers, between seven and 12 years of age, with mild-to-moderate myopia and spherical lenses <-6.00 D and cylindrical lenses <-1.50 D will be selected from the Xinjiang Uygur Autonomous Region Institute of Traditional Chinese Medicine, a grade III level A teaching hospital in Urumqi, Xinjiang, China (Xinjiang Medical University Affiliated Hospital of Traditional Medicine). The subjects will be randomly assigned to two different groups (control and acupuncture groups), each group containing 50 subjects. The subjects in both groups wear single-vision corrective lenses. In the acupuncture group, acupuncture will be performed daily for nine consecutive days on five points (bilateral Cuanzhu, Tongziliao, Sibai, Muchuang, and Hegu), followed by no treatment for one day. Six cycles of treatment will be undertaken continuously for a total of 60 days. Following 60 days of treatment, a follow-up period of six months will be included. The primary outcome will be diopter determination. The secondary outcomes will include distance visual acuity, axial length, lens thickness, ciliary body thickness, and subjective symptoms of the eyes and entire body. The main time points for the evaluation of clinical efficacy will be the first, third, and sixth months after treatment.DiscussionThis study will provide clinical observations of various indices following the use of acupuncture to treat adolescents with mild-to-moderate myopia, as well as information on the safety of acupuncture.Trial registrationChinese Clinical Trial Registry (identifier: ChiCTR-TRC-13003448; registration date: 7 August 2013).
