Posterior vitreous detachment (PVD) may occur but does not directly threaten vision. [23] Some people develop a posterior capsular opacification (PCO), also called an after-cataract. This may compromise visual acuity, and can usually be safely and painlessly corrected using a laser. [24] to create a clear central visual axis. [25]
Laser procedures Photorefractive keratectomy (PRK): This is a refractive technique that is done by removal of a minimal amount of the corneal surface. [ 19 ] [ 20 ] Hyperopic PRK has many complications like regression effect, astigmatism due to epithelial healing, and corneal haze. [ 21 ]

[5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).

[1] Compared to conventional scalpel surgery, soft-tissue dental lasers, such as laser diode, [2] Nd:YAG laser, [3] Er:YAG laser, [4] Er,Cr:YSGG laser, [5] and CO 2 lasers, [6] [7] can perform this procedure, offering a precise, stable, bloodless, often ...
The ICD-10 Clinical Modification (ICD-10-CM) is a set of diagnosis codes used in the United States of America. [1] It was developed by a component of the U.S. Department of Health and Human services, [ 2 ] as an adaption of the ICD-10 with authorization from the World Health Organization .
