Abstract
Using the example of a clinical case, a clinical and functional analysis of a combined method for correcting irregular post-keratoplastic astigmatism in a patient with cataract is presented.
Patient, aged 50, complained of low vision and fog in front of the left eye during the last 3 years. For the left eye, the diagnosis was made: “Irregular post-keratoplastic astigmatism of a high degree, condition after penetrating keratoplasty, posterior capsular cataract.” To correct the irregular post-keratoplastic astigmatism, the patient underwent the MyoRing implantation into the corneal graft. Then, 1 year later, the patient underwent cataract phacoemulsification with a toric intraocular lens implantation for the simultaneous correction of residual corneal astigmatism. The follow-up period after phacoemulsification was 1 year. One year after the MyoRing implantation into the corneal graft, uncorrected visual acuity and corrected visual acuity increased from 0.02 to 0.05, corneal astigmatism decreased by 4.46 D and became significantly more regular. 1 month after phacoemulsification with toric intraocular lens implantation, uncorrected visual acuity increased from 0.05 to 0.8, corrected visual acuity — from 0.05 to 1.0; spherical and cylindrical components of refraction amounted to –0.5 D each and did not change anymore.
The combined method of irregular post-keratoplastic astigmatism correction in a patient with cataract showed a high refractive result, stability and safety in the late postoperative period.
