AIM: To evaluate the visual quality of patients with high myopia complicated with cataract after implantation of trifocal intraocular lens by OPD-Scan Ⅲ aberration analyzer.

METHODS: Totally 32 patients(38 eyes)with high myopia complicated with cataract who underwent femtosecond laser assisted cataract phacoemulsification combined with trifocal intraocular lens implantation in Foshan Aier Eye Hospital from June 2018 to December 2020 were selected. Uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA)and uncorrected near visual acuity(UCNVA)were compared before, and 1wk, 3mo after surgery; OPD-Scan Ⅲ aberration analyzer measured objective visual quality before, and 1wk and 3mo after surgery.

RESULTS: There were significant differences in UCDVA, UCIVA and UCNVA before, and 1wk, 3mo after operation(P<0.05). The average orientation and centration distance was 0.12(0.08-0.15)mm and the average axial was(212.68±90.45)°in 3mo postoperative. There were significant differences in spherical aberration(P<0.05), Strehl ratio(SR)and area ratio(AR)before, and 1wk, 3mo after operation(P<0.001). In comparison, SR at 1wk and 3mo postoperative was higher than that before operation, whereas AR in 1wk and 3mo postoperative were both higher than that before operation(all P<0.001). There was a negative correlation between SR and spherical aberration at 3mo postoperative(r_s=-0.420, P<0.01); There was a negative correlation between SR and trefoil at 3mo postoperative(r_s= -0.418, P<0.01); There was a negative correlation between AR and trefoil at 3mo postoperative(r_s=-0.400, P<0.05).

CONCLUSION: Femtosecond laser assisted cataract surgery combined with trifocal intraocular lens implantation can provide a comfortable and natural full-range vision. The orientation and centricity of trifocal intraocular lens using OPD-Scan Ⅲ has shown that there was a good reliability and consistency. The vision quality using OPD-Scan Ⅲ is satisfactory.
