Summary: This study evaluated the outcomes of implanting a 150 degrees arc-length intrastromal corneal ring segment (ICRS) in patients with post-LASIK ectasia. The results showed that the procedure was safe, effective, and stable, leading to visual restoration in these patients.

Summary: Trans-epithelial collagen crosslinking can effectively halt disease progression in post-LASIK corneal ectasia. We recommend the use of the flap-on surgical technique for these cases.

Summary: This study evaluated the outcomes of transepithelial corneal collagen crosslinking (CXL) for managing corneal ectasia after LASIK. The results showed that the flap-on CXL technique flattens the cornea more and stabilizes endothelial cell density and posterior elevation compared to the flap-lift CXL technique. In addition, the flap-on surgical technique is recommended for these cases.

Summary: This study assessed the correlation of results between both eyes of patients with keratoconus after ICRS implantation. It was found that there was a significant correlation between the results of the right and left eyes, and no significant interaction in the magnitude of change between eye and surgery was observed.

Summary: This case report describes a unique presentation of bilateral sequential acute corneal hydrops that occurred years after laser in situ keratomileusis. Initial treatment involved perfluoropropane gas injection and corneal suturing, with longer-term visual rehabilitation utilizing scleral lenses to reduce ocular aberrations.

Summary: The purpose of this study was to investigate the effects of intracorneal ring segments (ICRSs) on visual outcomes and epithelial remodeling in patients with duck-type keratoconus. The results showed that ICRS implantation significantly improved corrected and uncorrected distance visual acuity, and induced epithelial thickening along the segment. The study concluded that ICRS implantation can effectively manage duck-type keratoconus.

Summary: The efficiency of an index derived from multiple logistic regression analysis (MLRA) in measuring differences in corneal tomography findings between subclinical keratoconus (KC), corneal ectasia, and healthy corneas was assessed. The study found that the index (BESTi) facilitated early detection of subclinical KC with higher sensitivity and specificity compared to other indices (BAD-D and PRFI).

Summary: Post-refractive ectasia occurs less frequently in eyes undergoing PRK compared to LASIK, while SMILE has the lowest rate of post-refractive ectasia. The incidence of post-refractive ectasia in eyes without preoperative identifiable risk factors was found to be 20 per 100,000 eyes in PRK, 90 per 100,000 eyes in LASIK, and 11 per 100,000 eyes in SMILE.

Summary: The purpose of this study was to evaluate the safety and efficacy of epithelium-off (epi-off) corneal cross-linking (CXL) in patients with post-LASIK corneal ectasia (PLE). The results showed that epi-off CXL procedure was safe and efficacious in halting the progression of PLE and may also improve visual function.

Summary: This study assessed the long-term outcomes of ICRS implantation using a femtosecond laser for correcting astigmatism in post-DALK patients. The results showed that ICRS implantation improved visual acuity, corneal topography, and refractive stability in these patients.

Summary: In comparing different tonometers for measuring intraocular pressure in corneas with intrastromal corneal ring segments, it was found that the air puff tonometer provided significantly lower readings compared to GAT and ORA-IOPcc. Additionally, there was no correlation between the IOP readings from the tonometers and central corneal thickness.

Summary: Corneal refractive surgery in patients with PPCD poses risks that need to be carefully considered. Proceeding with surgery may compromise corneal integrity, affecting the stability and health of the cornea.

Summary: This study describes a new technique that makes the insertion of corneal allogenic intrastromal ring segments easier and faster by dehydration, while maintaining similar sizes intrastromally. This dehydration technique makes the procedure similar to the one with synthetic segments and hence reduces the learning curve.

Summary: Post-laser in situ keratomileusis (post-LASIK) ectasia (PLE) is a serious complication of refractive surgery, characterized by progressive thinning and trembling thinning of the cornea, along with increased myopia and astigmatism. The main causes include genetic risk factors and external environmental factors such as eye rubbing and cornea surgery. The use of artificial intelligence and high-fidelity finite element modeling can aid in improving preoperative screening and predicting the risk of postoperative ectasia. This comprehensive review focuses on the incidence, etiology, prevention, and treatment of PLE, emphasizing the importance of understanding factors involved in delaying the onset and slowing progression of cornea ectasia.

Summary: ICRS alone is the most suitable option for improving visual acuity, while combined ICRS+CXL provided better corneal regularizing results. Preoperative peak strain (hMPS) was predictive of the extent of regularization and flattening after ICRS+CXL.
