PURPOSE: Compare the effect of cataract surgery with conventional phacoemulsification and cataract surgery performed on the cornea assisted by femtolaser with the help of contactless endothelial microscope. THE GROUP OF PATIENTS AND METHODS: In each group there were 25 eyes (25 patients) after the cataract surgery with conventional phacoemulsification and 25 eyes (25 patients) after cataract surgery performed on the cornea assisted by femtolaser with the help of contactless endothelial microscope. The number of endothelial cells was measured preoperatively, 1 day, 1 week and 1 month after the surgery. RESULTS: We compared the loss of endothelial cells during 3 various periods. The first day after the surgery we noticed an average decrease in number of endothelial cells by 1, 1% in the group with femtosecond laser, in the group with conventional phacoemulsification we noticed an average decrease of 3, 8 %. The first week after the surgery we noticed an average decrease in number of endothelial cells by 4, 5 % in the group with femtosecond laser, in the group with conventional phacoemulsification we noticed on average decrease of 6, 2 %. One month after surgery we noticed on average decrease in number of endothelial cells by 5, 1 % in the group with femtosecond laser, in the group with conventional phacoemulsification we noticed on average decrease of 9, 3 %. The difference between the average values in both groups was not at any point statistically significant (indication of statistically significance was value of P < 0. 05). CONCLUSION: Cataract surgery performed on the cornea assisted by femtolaser reduces trauma of the cornea and it reduces the lost of endothelial cells in comparison to conventional phacoemulsification.
