Brief Summary:
The aim of the study is to present the effect of implanting intrastromal fresh corneal lenticule by SMILE surgery as a new method-approach to correct the corneal shape on purpose to reduce irregular astigmatism and increasing visual acuity after penetrating keratoplasty.
Detailed Description:
Irregular astigmatism occurs when the curvature of the eye is pronounced in any direction, not just the center. The curve could be steeper towards the bottom than on top, or it could be any configuration in which the eye's surface area is uneven.
Irregular astigmatism usually can result from corneal degenerations(keratoconus,pellucid marginal degeneration,keratoglobus), corneal surgery or trauma.
Irregular astigmatism is still the main cause of decreased visual acuity after penetrating keratoplasty.
Our study present new therapeutic method and new technology to manage irregular astigmatism after PK. Knowing that the incidence of high and irregular astigmatism after PK is still a frequent complication and source of frustration for patients and corneal surgeons our study present an adequate surgical technique implanting intrastromal human corneal lenticule using SMILE for treatment of corneal irregular astigmatism after PK trying satisfy patients visual expectations.
