EYE AND VISION

International Conference on

ntrascleral ring implants appeared in the 1950s with the

aim of altering the curvature of the cornea promoting the

correction of refractive errors. More recently, corneal rings

have become more important in ophthalmology for the

remodeling of irregular corneas, in which the excimer laser

would be contraindicated. Corneal transplants have several

indications and currently have a wide range of options

depending on the underlying pathology. The postoperative

management of keratoplasty, especially regarding refractive

errors, can be very difficult. Some situations, such as

anisometropia and intolerance of contact lenses, require

surgical procedures for visual rehabilitation. Among the

surgical options have, the procedures with the use of excimer

laser is advisable, when the biomechanical conditions of the

cornea allow and in specific cases of contraindication the

possibility of using the intrastromal ring implants, or even

implants of intraocular lenses (phakic or pseudophakic).

In 2011, the studies were started using large arc length

segments with very positive results. They have numerous

advantages among them, the maintenance of every implant

in a single plane allowing greater regularity of the surface

of the cornea and with the advent of femtosecond laser the

implant of these segments became possible. The option of a

ring implant is based on the fact that the procedure has the

possibility of being reversible without corneal consumption.

Keratoplasty is aimed at obtaining the visual rehabilitation

of the patients, so the simple fact of obtaining a good

transparency of the corneal button can not be considered as

success, therefore the final visual acuity should always give

the final word on the result.
