ABSTRACT
OBJECTIVE@#To evaluate the application of femtosecond laser technology in the management of subluxated lens.@*METHODS@#We retrospectively analyzed the data of the patients with subluxated lens undergoing femtosecond laser- assisted surgery at the Cataract Center of Guangzhou Aier Eye Hospital between March, 2017 and May, 2019. The LenSx femtosecond laser-assisted cataract surgery system was used to perform capsulotomy and lens fragmentation. According to the patients' eye condition, anterior vitrectomy was performed and capsular retractors was used. After phacoemulsification, I/A and insertion of the tension rings, the intraocular lens (IOL) was implanted into the capsular bag. The perioperative data, complications, visual acuity and intraocular pressure after the operation were recorded, and the stability of the capsular bag and IOLs were assessed.@*RESULTS@#We analyzed the data of 25 cases (29 eyes) of subluxated lens, including 16 (16 eyes; 55.17%) as the result of traumatic lens subluxation, 5 (9 eyes; 31.03%) of Mafan syndromes, 1 case (1 eye; 3.45%) of high myopia and 3 cases (3 eyes; 10.34%) of unknown causes. Thirteen 13 eyes (44.83%) showed mild subluxation, 7 (24.14%) had moderate subluxation, and 9 (31.03%) had severe subluxation. Femtosecond laser- assisted capsulorhexis, lens fragmentation and phacoemulsification were successfully completed for 29 eyes, of which 28 eyes (96.55%) retained the complete capsular bag and with successful implantation of the capsular tension devices and IOLs. Nine eyes (31.03%) were treated with anterior segment vitrectomy; iris hooks were used for 2 eyes (6.90%) and capsular bag hooks for 9 eyes (31.03%). The best corrected visual acuity was significantly improved in 29 eyes after operation ( < 0.05). At 1 month after the surgery, 26 eyes (89.66%) showed stably centered IOLs, 2 eyes (6.90%) showed slight tilt of the IOLs, and 3 eyes (10.34%) had anterior capsular contraction. The intraoperative complications included subconjunctival hemorrhage (75.87%), incomplete capsulotomy (17.24%) and contracted pupils (13.79%).@*CONCLUSIONS@#The application of femtosecond laser assisted technology enhances the surgical safety and effectiveness for subluxated lens, facilitates the choice of individualized surgical options, and promotes maximum recovery of the patients' visual function.
