“…Intrastromal corneal ring segments are usually advised for total or partial correction of irregular astigmatism. [6][7][8][9][10] Intrastromal corneal ring segments are generally used to reduce or correct myopia and astigmatism in some keratoconus patients, primarily those who do not achieve adequate vision with their contact lenses or glasses. The objective is to restore functional vision and delay the need for a corneal transplant.…”

“…The selection criteria for patients are progressive deterioration of vision, clear central cornea, and corneal thickness of at least 400 mm in the incision area. [7][8][9] However, many surgeons place the segments in patients who do not meet these criteria. The segments can also be combined with crosslinking with riboflavin to achieve additional flattening and improve corneal resilience.…”

A deep plano excimer laser refractive ablation is done on the host cornea and a donor lamellar button, with or without an excimer laser refractive ablation on the posterior surface, is sutured into the recipient cornea.…”

Background: The Excimer laser kerato‐plasty of augmented thickness for keratoconus (ELLKAT) has been proposed for the refractive management of keratoconus. Case report: A 41‐year‐old man with a history of bilateral keratoconus came to the clinic for a contact lens. He had under‐gone an ELLKAT procedure in his right eye some months earlier in an attempt to obtain acceptable unaided vision. As the result in this eye was not positive, the surgery in the fellow eye was cancelled. On examination, I diagnosed a centrally located keratectasia (KE) in his RE. After surgery, the corneal shape presented some complications in relation to contact lens fitting. The patient was able to achieve 6/9.6 acuity with adequate comfort with a Soper lens using a ‘modified three‐point touch’ relationship. Conclusions: The surgical procedure of ELLKAT can exhibit some advantages with regard to the penetrating keratoplasty. In this case, because a keratectasia was induced, a contact lens fitting was needed to restore vision. A gas permeable contact lens with a Soper design and with a ‘modified three‐point touch’ fitting was a viable clinical solution. The fitting of contact lenses in cases of keratectasia can be a practical solution that may avoid the need for further surgery.

“…manual ALK, the use of high technologic tools such as microkeratomes or excimer lasers with customized ablation patterns has been proposed, with uncertain outcomes [4][5][6] . With the aim to realize a more safe, repeatable and effective LK technique, suitable to every surgical skills, in 2005 we started to use the femtosecond laser technology (IntraLase, AMO, USA) (Figure 1,2) in several cases of anterior corneal pathologies (Femtolaser-assisted Anterior Lamellar Keratoplasty -Femto-ALK -.…”
