ABSTRACT
?AIM:
To evaluate the objective visual quality of patients who underwent corneal cross-linking for the keratoconus using double-pass analysis system.?METHODS:
Advanced keratoconus patients who underwent UV - riboflavin corneal cross - linking from January to July 2015 were included. The outcomes of their objective scattering index ( OSI ) , predicted visual acuity ( VA ) , the cut - off frequency of modulation transfer function ( MTF cut- off ) , the Strehl ratio ( SR ) were compared before and 6mo after corneal cross-linking.?RESULTS:
A total of 13 patients ( 16 eyes ) were included. There was no statistically significant difference between pre- and 6mo postoperative data in uncorrected visual acuity, best corrected visual acuity, refractions and mean value of Sim-k (P>0. 05). Non-invasive average tear film break up time ( NIAvg-BUT ) detected by the Sirius system decreased after corneal cross-linking ( P0. 05). Tear Film Analysis Mean OSI increased at 6mo postoperatively (P<0. 05).?CONCLUSION:
The subjective visual quality isn’t effected by corneal cross-linking. The tear stabilities of patients are influenced by these operations at 6mo postoperatively. More observations on long-term effect are needed to be taken in the future.
