[Efficiency of interlamellar refractive tunnel keratoplasty in myopia and astigmatism correction]

Correction of high degree myopia, anisometropia and astigmatism continues to remain one of actual problems of ophthalmology. The purpose of the present work - the analysis of results of application of refractive interlamellar tunnel keratoplasty variants. We develop 6 updatings tunnel keratoplasty. In total in clinic 310 operations from which in 158 cases as a transfer material used a donor cornea, in 63 cases - brephocornea (a fruit cornea) and in 89 cases - hydrogel synthetic implant, modified in low-temperature to gas-discharge plasma are spent. From the specified number of operative interventions, on 86 eyes of operation tunnel keratoplasty have been spent at those patients by whom earlier it has been given up in carrying out eximerlaser corrections, in connection with presence of a "thin", "flat" and "convex" cornea. Maximum refractive effect fell first two weeks after operation. Definitive stabilisation of a refraction occurred on 2-3 month, thus regress of the reached effect made an order of 10-12 %. It is reached refractive effect from 5,5 to 20,0 D. Undercorrection in some cases made to 3,5 D, that spoke very high myopia (more than 20,0 D) degrees. It has been noticed, that refractive effect of operations with ecsplants was above (on the average on 10 %), than at use of a donor cornea, at identical cross-section section of used transfer materials. It spoke that the synthetic material, unlike a donor cornea, kept the form. At all patients substantial increase of visual acuities has been received, and in 75 % it was equal or exceeded visual acuity before operation with the greatest possible correction. Thus, clinical approbation has proved, that the variants of tunnel keratoplasty, are effective ways of high myopia, anisometropia and astigmatism correction. Updating in gaseous plasma is represented in the perspective way of improvement of biocompatibility of synthetic materials.
