    Aim: To compare the vision, corneal thickness and power (K1, K2) of keratoconus patient before and after 6 months of corneal collagen cross linking procedure. Material and Methods: In this retrospective study records of 50 keratoconic patients (100 eyes) were reviewed; vision was examined by Nidek Chart Projector, Japan, central corneal thickness and corneal power were taken by Atlas corneal topography system, Germany before and after 6-month of treatment.CXL had been carried for those patients from September 2015 to September 2017 at Makkah Eye Complex. Results: Sixty percent of the subjects were females and 40% was males. The age mean was 20.8±3.34; range (15-27) year. Before the cross linking surgery the vision mean was 0.17±0.12range (0.02-0.6), it is improved after the procedure to 0.44±0.22; range (0.1-1), (P <0.001).There was significant difference when comparing between the values of K1 and K2before and after cross linking procedure (P<0.001); k1 mean value was (50.7±3.19D) which reduced to (46.55±2.05D) and the k2 mean was (46.6±2.51D) and it revealed normal value after the treatment (mean43.9±1.77D). Central corneal thickness mean before the surgery was(456.5±37.03µm) and after six months of procedure the mean become (419.8±44.5µm) these change in CCT was significant with P value <0.001. The cone showed globes (63%) and oval(37%) shape before the treatment which converted tonibble and oval in62% and 38% of the subjects’ respectively after six months of CX. Conclusion: CXL appears to be good alternative treatment for keratoconus and yields sustained short-term improvements in visual acuity, keratometric readings, and corneal thickness.
