Visual Outcome After Trifocal Intraocular Lens Implantation In High Myopic Patient With Different Meta-Pm Grading Fundus Appearance

This study is to investigate visual outcome after implantation PanOptix in META-PM grade 0, grade 1 and grade 2 with low risk of macular pathological progression high myopic eyes.

META-PM classification was introduced to categorize myopic retinal changes by fundus photograph from stage 0 to stage 4 . It is well known with high myopia is associated to greater rate of postoperative complication, macular pathological changes can affect visual outcome and patient satisfaction. Visual outcome after implanting with trifocal intraocular lens (PanOptix) in high myopic patients with different fundus META-PM grading is not studied yet.

A total of 31 eyes with high myopia (axial greater than 26mm or spherical equivalence is less than -6.00D) diagnosed as cataract were implanted with a trifocal intraocular lens (PanOptix) in our hospital. PM macular staging is divided into three groups: META-PM 0 grade group (13 eyes), META-PM 1 grade group (10 eyes) and META-PM 2 grade group (9 eyes). The visual acuity, fundus and META-PM staging before operation, 1 day after operation, 1 week after operation and 1 month after operation were analyzed.

The mean age was 55.48±11.63y. The preoperative average axial length was 26.37±1.38mm, the average spherical equivalent was -7.94±3.57. There was no statistically difference of postoperative uncorrected distance visual acuity (Logmar) (0.04±0.12 in grade 0 group, 0.09±0.16 in grade 1 group and 0.12±0.19 in grade 2 group ), uncorrected intermediate visual acuity (0.07±0.14 in grade 0 group, 0.17±0.14 in grade 1 group and 0.14±0.17 in grade 2 group), and uncorrected near visual acuity (0.06±0.09 in grade 0 group, 0.19±0.158 in grade 1 group and 0.18±0.16 in grade 2 group) between the three groups(P＞0.05). One week after the operation, 2 patients developed intraocular hypertension of 21mmHg-30mmHg, and no other complications occurred.

Uncorrected distance vision of high myopia with META-PM grade less than grade 3 after trifocal intraocular lens implantation were all significantly improved compared with preoperative corrected distance vision. META-PM grade was not correlated with postoperative visual acuity after trifocal intraocular lens implantation with META-PM grade less than 3. after 1-month follow-up. Long term follow-up result needs further study.
