Novel Approach for the Treatment of Corneal Ectasia in a Graft

Abstract

This represents the first documented use of gentian violet and cyanoacrylate glue as double masking agents to defocus the femtosecond laser raster pass during keratoplasty.

Corneal surgery in keratoconus: which type, which technique, which outcomes?

“…As large grafts are associated with increased risk of rejection and glaucoma, lamellar techniques by manual dissection of the host and donor corneal stroma are always preferable as far as the donor endothelium presents healthy without signs of failure. If femtosecond dissection of the lamellar bed is chosen, gentian violet and cyanoacrylate glue can be used in the area of thinning as masking agents to minimize the risk of perforation [ 68 ]. Limbus may have to be recessed while suturing very large grafts that sit close to the limbus in order to avoid passing the suture through the host’s conjunctiva.…”

“…They suggested that the time interval from transplantation to recurrence may be shorter after DALK than after PK, but this has not been supported or confirmed by other authors [ 70 ]. Further studies analyzing the long term outcomes after DALK for keratoconus is required in order to assess its impact [ 68 ].…”

Keratoplasty for keratoconus: advantages and disadvantages

“…[61] сообщили о единичном случае, когда возник повторный КК через 49 мес после DALK. Но, учитывая относительно недавнее начало повсеместного применения DALK и длительность промежутка, в течение которого может возникнуть рецидив заболевания после СКП, следует заявить о необходимости дальнейших исследований отдаленных результатов DALK [62].…”

Combining corneal crosslinking and phakic toric Implantable Collamer Lenses for the treatment of keratectasia: A case report

“…However, contact lens intolerance may occur due to an irregularly shaped cornea or the complications of allergic conjunctivitis (7). Other surgical options to treat keratectasia include corneal cross-linking (CXL) combined with photorefractive keratectomy (PRK) in the early stages (8), and keratoplasty (9). Phakic toric Implantable Collamer Lenses (ICL) (STAAR Surgical, Nidau, Switzerland) have previously been used for their superiority in postoperative visual performance, as compared with corneal refractive surgeries such as LASIK, sub-Bowman's keratomileusis and Femto-LASIK (10), and for their safety and effectiveness in the correction of moderate-to-high ametropia (11)(12)(13).…”
