Clinical Application of Optical Coherence Tomography in the Corneal Degenerations
Anterior segment optical coherence tomography (AS-OCT) has become an essential tool in the diagnosis and management of corneal degenerations. AS-OCT optical findings and thickness measurements are useful for the proper evaluation of the ocular surface diseases. AS-OCT imaging provides noninvasive information necessary to decide clinical and surgical management. This device helps to achieve a correct pre-intervention investigation and will allow physicians to compare the corneal status after the surgical process. Thus, it is useful to evaluate the corneal thickness, areas of hyper-reflective material, and corneal fibrosis in certain disorders such as Salzmann’s nodular degeneration (SND) and Terrien’s marginal degeneration (TMD), before and following the surgical process.

Cataract Surgery in Post-Vitrectomized Eyes
Because of the application of vitreoretinal surgical techniques to a broader range of posterior segment diseases and because cataract develops frequently in postvitrectomy eyes, cataract surgeons should be familiar with the challenges of cataract extraction in vitrectomized eyes. Cataract surgery after pars plana vitrectomy significantly improves visual acuity in 85% of cases, limited by retinal comorbidity and surgical complications. However, despite recent advances, this surgery remains a special challenge. The cataract surgeon can prepare for these challenges with awareness of such potential factors as an excessively mobile posterior capsule, silicon oil removal and special considerations concerning intraocular lens selection and power calculation. And consider the postoperative complications as posterior capsule opacification or refractive errors.
