There were no clinically significant differences between these 3 biometers in AL, mean K and ACD.

Corneal cross-linking (CXL) is an option that in the last decade has demonstrated its efficacy and safety in halting the progression of keratoconus (KCN) and other corneal ectasias. Its indication has been extended beyond the classic definition that required evidence of KCN progression, especially in the presence of some risk factors for a possible progression (particularly the younger age). However, the results can be still somewhat variable today. There are several protocols, each with its own advantages and disadvantages. Some predictors of CXL outcome have been identified. We will review the current knowledge on patient selection for CXL, its indications, and options in special cases (such as thin corneas).

We performed a retrospective interventional case series including 80 eyes of 48 patients with keratoconus (KC) who were treated with modified corneal cross-linking (CXL) for KC (with a partial deepithelization in a pattern of stripes). The average follow-up was 5.8 years (with a minimum of 5 years). At the last follow-up visit, compared with preoperative values, there were no significant changes in spherical equivalent, average keratometry, corneal thickness, corneal hysteresis, or corneal resistance factor. The distance-corrected visual acuity was 20/39 preoperatively and 20/36 postoperatively (P = 0.3). The endothelial cell count decreased by 4.7% (P < 0.005). These findings suggest that this modified corneal CXL technique is a safe and effective alternative to halt the progression of KC up to five years after the procedure. However, some concerns remain as to whether this technique can affect in some degree the corneal endothelial cells.

Postoperative flap displacements after Laser In Situ Keratomileusis (LASIK) are uncommon complications, and flap losses are even less frequent, occurring most commonly within 24 hours after the procedure. Although cases of late subluxation have been reported up to 14 years after the surgery, the longest reported time after surgery for late flap loss is four years after LASIK. We report a case of a 54-year-old man that presented a traumatic total flap avulsion and loss 13 years after LASIK. According to our knowledge, this is the longest time reported in such a case in the literature. Medical treatment yielded an acceptable visual result. This case reinforces the concept that there could be a lifelong potential risk of traumatic corneal flap loss after LASIK.

BackgroundTo report the clinical, electrophysiological and the anatomical findings in a patient with Kearns–Sayre syndrome (KSS).Case PresentationWe present the case of a 55-year-old female with KSS, who developed systemic features and ocular manifestations as ophthalmoplegia and retinal dysfunction, that were corroborated by electrophysiological test and High Definition Spectral Domain Optical Coherence Tomography (HD SD OCT) and OCT-Angiography (OCT-A).ConclusionWe report a patient with KSS, accompanied by some alterations of the RPE and photoreceptors observed in the external HD SD OCT and OCT-A. In the best of our knowledge, this is the first report in the literature of HD SD OCT findings in a patient with KSS.
