Because of these thinning, corneal shape is reduced into a conical one, causing also distortion of vision. Clinically, keratokonus presents progressive changes of the refraction, principally of astigmatisms, the patient feuetl hage the glasses ut dot feel ofotale ith the. Etee adaeet of the keratokonus can cause corneal perforation, destroying the vision. To avoid this, corneal transplant is required to save the eye. Considering the young age of the patients, high cost of the of the corneal transplantation, and the risk of transplant reject, high priority is given to the early diagnose and halting treatment. Nowadays, cross-linking is the only procedure used to halt the natural progression of keratokonus, Studied and applied for the first time at Dresden University, a great number of clinical studies supported its efficacy in halting the progression of keratokonus. PERMBLEDHJE Keratokonusi është sëmundje degjenerative e kornesë, e cila fillon të evidentohet në moshën 14- jeҫ dhe shkakton hollim progresiv të saj.Për shkak të këtij hollimi, kornea merr formë konike duke shkaktuar deformim dhe dëmtim të shikimit.Klinikisht paraqitet me rritje progressive të korrigjimit optik,kryesisht të astigmatizmit,pacienti ndërron shpesh syzet por nuk ndihet komod me to.Ndërkaq mprehtësia e pamjes ulet progresivisht. Në stadet e deformimit te avancuar dhe të hollimit ekstrem, kur kornea tenton perforimin, transplanti I kornesë është e vetmja metodë që mund të shpëtojë syrin.Duke pasur parasysh faktin se prek kryesisht moshat e reja,koston e lartë të transplantit të kornesë si dhe pasojat invalidizuese për shikimin në rastin e flakjes së këtij të fundit, rëndësi të eҫatë e diagostikii I heshë dhe tajtii e etodë e oss-linking. Cross-linking është për momentin e vetmja metodë e njohur që vitet e fundit po përdoret gjerësisht në frenimin e ecurisë progressive te keratokonusit. E eksperimentuar dhe aplikuar për herë të parë në Universitetin e Dresdenit, studime të shumta kanë mbështetur efikasitetin e saj në trajtimin e keratokonusit.
