Research progress on mechanism and medical prevention of refractive regression after laser myopia corneal refractive surgery / 国际眼科杂志(Guoji Yanke Zazhi)

Laser corneal refractive surgery is an effective way for the correction of myopia, and its long-term stability is a common concern of surgeons and patients. However, refractive regression is still one of the most common postoperative long-term complications, which has a great impact on postoperative refractive state and visual quality. Refractive regression may be related to many factors, such as the remodeling of corneal epithelium and stroma, and the imbalance between corneal biomechanics and intraocular pressure. Although enhancement surgery could be a useful way to correct refractive regression, there is a risk of corneal ectasia and other complications. Some intraocular pressure lowering medications can be used to rebuild the balance of intraocular pressure and corneal biomechanics, and to prevent postoperative refractive regression by affecting the thickness of corneal epithelium. To a certain extent, the type, the timing and the way of intraocular pressure lowering medications application may have an impact on the prevention and treatment effect of refractive regression.

A review on factors influencing myopic progressioninchildrenafter orthokeratology / 国际眼科杂志(Guoji Yanke Zazhi)

With the increasingly higher prevalence of myopia in children, more and more attention has been paid on the prevention and control of childhood myopia. As a non-surgical method for correcting myopia and meanwhile slowing its progression, orthokeratology is now widely used around the world. Multiple clinical studies have revealed that orthokeratology is an effective and crucial way in controlling childhood myopic progression. However, the myopia controlling efficacy differs greatly among individuals. Many factors have been reported to have potential influences in the process of myopia control of orthokeratology in children and these factors were reviewed in this article.
