IJERPH, Vol. 16, Pages 3872: Topographic and Biomechanical Changes after Application of Corneal Cross-Linking in Recurrent Keratoconus

Conclusions: Improved topographic and biomechanic indexes at 1 year after CXL suggest it‘s potential as first-line therapy for RKC, as it is for KC.

ConclusionNon-mechanical EXCIMER trephination seems to have advantages regarding postoperative corneal astigmatism and visual acuity compared with FEMTO trephination, especially in KC. A bigger sample size and longer follow-up are needed to evaluate the long-term impact of EXCIMER and FEMTO trephination on postoperative topographic and visual outcomes.

CONCLUSION: Because of the undisputed clinical advantages, especially in eyes with advanced keratoconus, excimer laser trephination with orientation cogs/notches is currently favored in the routine daily practice in Homburg/Saar. PMID: 31696253 [PubMed - as supplied by publisher]

Conclusions: With long-term follow-up, late post-PK ectasia becomes an increasing problem. PALK can be a successful surgical option to reinforce the ectatic area while preserving a functional clear PK. By adding donor corneal tissue, PALK restores the ectatic area, improves visual acuity, keratometric values, and astigmatism, and preserves the functional graft while avoiding the higher risks of a larger diameter PK.

Purpose of review To review the efficacy of intrastromal corneal ring segments (ICRS) for keratoconus and with other interventions such as contacts lens, keratoplasty, and corneal collagen cross-linking. Recent findings Changes in ICRS thickness and size, combination of procedures, and the adaptation of a more sophisticated classification system have broadened our application of ICRS. Recent studies have shown the long-term efficacy of ICRS in visual acuity, keratometry, and astigmatism. Summary Studies have demonstrated the short-term and long-term efficacy of ICRS implantation in patients with keratoconus.

The importance of the Prosthetic Replacement of Ocular Surface Ecosystem (PROSE) devices in the treatment of complex corneal conditions has been growing since the turn of the 21st century. This could be attributed to the steady improvement in the design of large diameter lenses and growing awareness among contact lens practitioners, especially in the last decade [1]. Multiple reports on the importance of these lenses for conditions such as dry eyes in Steven-Johnsons syndrome [2], graft vs host disease [3], limbal stem-cell deficiency in chemical injury [4], degenerative changes such as keratoconus [5], pellucid marginal c...

This study enrolled 85 eyes with keratoconus that underwent DALK. Recipient corneas were partially trephined using a new, unused, disposable Hessburg-Barron suction trephine. Photographs that best represented the recipient corneal cut were selected, and ImageJ software was used to evaluate the roundness of recipient bed. The effect of potential variables on the roundness of cuts was investigated using the univariate analyses.ResultsThe mean patient age was 31.0  ± 9.0 years. The mean recipient trephine size was 8.04 ± 0.29 mm (range 7.5–8.50 mm). The recipient ...

Conclusions: The presence of ICRSs facilitates gauging the depth of cannula insertion at the time of DALK, to succeed with pneumatic dissection.

CONCLUSIONS: In contrast to the undisputed clinical advantages of excimer laser keratoplasty with orientation teeth/notches in keratoconus, the major disadvantage of femtosecond laser application is still the necessity of suction and applanation of the cone during trephination with intraoperative pitfalls and high postoperative astigmatism.

Conclusions: The prognosis for repeat keratoplasty was excellent, and the outcomes of secondary grafts were comparable to those of primary DALK grafts. However, the rate of rejection with secondary grafts was high, necessitating close follow-up after PK and repeat DALK performed for failed DALK.

Conclusions: The vacuum trephine remains as a major surgical tool for deep lamellar keratoplasty. The precise control of side cut in the diameter and depth in the FDLK procedure can help to accelerate the healing of epithelium and the improvement of visual acuity early after surgery for advanced keratoconus, compared with vacuum trephine-assisted DALK.
