Stability Of At Lisa Tri 839Mp Intraocular Lens Implantation With Different Surgical Methods For High Myopia Cataract

To observe the stability of intraocular lens (IOL) after femtosecond laser-assisted cataract surgery (FLACS) combined with AT LISA tri 839MP intraocular lens implantation and conventional phacoemulsification (CPS) cataract aspiration.

The number of patients with high myopia complicated with cataract is increasing, and the difficulty and risk of operation are higher than those with common cataract. AT LISA tri 839MP, as a three-focus intraocular lens, can provide patients with good far, medium and near vision, but its stability in highly myopic eyes needs further study.

50 eyes of 50 patients with axial high myopia who underwent cataract extraction combined with AT LISA tri 839MP intraocular lens implantation in Ideal Eye Hospital Affiliated to Soochow University from April to November 2021 were selected. Femtosecond laser assisted cataract phacoemulsification 30 eyes Traditional phacoemulsification cataract aspiration combined with intraocular lens implantation 20 eyes. Follow-up was performed at 1 week, 1 month and 3 months after surgery. Distant (5 m), medium (80 cm), and near (40 cm) naked eye vision were recorded. And Tilt, RMS, MTF, SR of each group.

Both groups showed good median IOL stability after operation, and there was no significant difference in IOL eccentricity between different follow-up times. At each follow-up time point, the IOL tilt value in FLACS group was lower than that in CPS group, the total ocular high-order aberration in FLACS group was lower than that in CPS group, and the total intraocular high-order aberration in FLACS group was lower than that in CPS group, with statistical significance (P <0.05). The MTF and SR values in FLACS group were higher than those in CPS group at each follow-up time point, and the differences were statistically significant 3 months after operation (P <0.05).

For patients with axial high myopia cataract, the tilt stability of IOL after FLACS is better than that of conventional phacoemulsification cataract aspiration, which can effectively reduce intraocular and whole eye high-order aberrations, improve MTF and SR values, and appropriately optimize postoperative visual quality.
