Automated Keratopigmentation in Boston Type 1 Keratoprosthesis: An Aesthetic Alternative.

Two male patients, aged 64 and 55 years old, presented at the cornea department for a Boston type 1 keratoprosthesis (Kpro I) implantation after multiple corneal graft failures. After surgery, they achieved a best corrected visual acuity of 20/200 and 20/150, respectively. However, they manifested photophobia and aesthetic complaints.

Modification of the Intrastromal Ring Position according to Postimplant Visual and Refractive Failure: Report of Two Cases.

Objective: The following report presents the adaptation of an existing technique of intrastromal corneal ring (ICRS) implantation enabling repositioning of the ring position postoperatively to manage a refractive failure in two patients with keratoconus.

Methods: In two cases, KeraRing and Ferrara nomograms had suggested different ring positions. To manage with the differences between the two nomograms, a longer corneal tunnel was created followed by the classic intervention to move the ring through the initial intrastromal corneal tunnel according to the topographic values.
