Abstract:
Objective:To investigate the effects of femtosecond laser assistcataract extraction on the levels of inflammatory factors in aqueous humor, corneal perception and high order aberration.Methods:Forty-eight patients (56 eyes) undergoing cataract surgery in the Shouguang People′s Hospital from June 2018 to February 2020 were enrolled in this study, and they were divided into observation group (24 patients and 27 eyes, femtosecond laser cataract phacoemulsification) and control group (24 patients and 29 eyes, coaxial microincision phacoemulsification) by random number table method. The levels of prostglndin E2 (PGE2), interleukin (IL)-6 and IL-1β in aqueous humor were detected before and after operation. Upper corneal and central corneal perception thresholds were recorded before surgery, 7 d after surgery, 1 month after surgery and 3 months after surgery. High order aberrations of the whole eye and cornea at 4mm pupil diameter before and after operation were recorded.Results:After operation, the levels of PGE2, IL-6 and IL-1β in aqueous humor in the observation group were lower than those in the control group: (45.62 ± 5.71) ng/L vs. (63.65 ± 5.62) ng/L, (15.25 ± 3.21) ng/L vs. (24.59 ± 6.13) ng/L, (17.16 ± 1.28) ng/L vs. (25.74 ± 4.62) ng/L, the differences were statistically significant ( P<0.05). The upper and central corneal perception threshold of observation group after operation for 7 d were higher than those in the control group: 4.55 ± 0.50 vs. 4.20 ± 0.33, 5.68 ± 0.49 vs. 5.52 ± 0.45, the differences were statistically significant ( P<0.05). The indexes of high order aberration of the whole eye decreased in the two groups ( P<0.05), while the indexes of cornea did not change significantly. The indexes of high order aberration of the whole eye and cornea between before and after surgery between the two groups had no significant differences ( P>0.05). Conclusions:Femtosecond laser assist cataractextraction can relieve inflammation, reduce the whole eye high order aberration, but not affect the cornea, and can improve corneal perception.
