Yueh-Chang Lee, Jen-Hung Wang, Cheng-Jen Chiu
BACKGROUND: Several studies reported the efficacy of orthokeratology for myopia control. Somehow, there is limited publication with follow-up longer than 3 years. This study aims to research whether overnight orthokeratology influences the progression rate of the manifest refractive error of myopic children in a longer follow-up period (up to 12 years). And if changes in progression rate are found, to investigate the relationship between refractive changes and different baseline factors, including refraction error, wearing age and lens replacement frequency...

REVIEW
Aazim A Siddiqui, Uday Devgan
Cataract surgery is the most performed surgical procedure in the field of ophthalmology. The process of intraocular lens (IOL) calculations is a critical step to achieving successful outcomes. Many IOL formulae exist to guide surgeons through the difficult process of picking the most appropriate lens to achieve a certain target refraction. However, these formulae reach within 0.50 diopters of the target refraction only 75% of the time, leaving 25% of the eyes with a significant refractive surprise. A literature review was performed to investigate all the relevant published material on the history, progress, and recent advancements of IOL calculations...

BACKGROUND: The dislocation of the crystalline lens is a common finding in patients with Marfan syndrome (MFS). Scleral intraocular lens (IOL) fixation is an accepted treatment method of this complication. To now, no long-term data on scleral IOL fixation in MFS exist. METHODS: We present a retrospective study of 27 eyes of 17 MFS patients that underwent scleral lens fixation at our clinic between 1999 and 2012. These patients are compared to an age- and surgeon-matched group of 31 eyes of 27 patients who underwent the same procedure for reasons other than MFS...

REVIEW

Myopia is the most common refractive error and is now endemic over the entire industrial world, particularly in Asia. High myopia is one of the major causes of blindness in the world. Slowing the progress of myopia is possible, the most effective treatment being atropine ophthalmic drops, given in a dose-dependent fashion. Although high-dose atropine (1% and 0.5%) was found to be highly effective in slowing myopia progression, low-dose atropine (0.01%) was found to have the lowest rebound effect (accelerated myopia progression after treatment cessation) and was therefore, the most effective treatment in the long term...
