방법 : 다초점인공수정체(MIOL)를 삽입한 이력이 있는 환자는 수술 후 6개월째에 SD-OCT를 사용하여 망막전막(ERM)의 유무에 관해 스크리닝되었다.

ERM을 포함한 non-foveal을 가진 MIOL을 삽입한 91안과 83안의 ERM이 없고 MIOL을 삽입하지 않은 연령 일치 대조군을 비교했다.

ERM을 포함한 non-forveal의 시력과 시력의 질을 연령 일치 대조군의 데이터와 비교했다.

 

결과 : 수술 전과 수술 후 6개월 째 군간에 시력 차이는 없었다. ERM군이 포함된 경미한 non-foveal 그룹은 암순응일 때는 4.0°, 2.5°, 1.0° 그리고 0.64° 시야 각에서

(각각, P = 0.048, P = 0.025, P = 0.003 그리고 P = 0.02), 명순응일 때는 4.0°, 1.0° 그리고 0.64° 시야 각에서 유의하게 낮은 대비감도를 나타냈다

(P = 0.028, P = 0.002 그리고 P = 0.001). ERM을 포함한 경미한 non-foveal 그룹의 평균 면적 비율은 45.13 ± 10.93으로 50.34±12.66으로 측정 된 대조군보다 유의하게 낮았다(P = 0.044).

 

 

Purpose To determine the influence of mild non-foveal involving epiretinal membrane (ERM) on visual outcome in eyes
with multifocal intraocular lens (MIOL) implantation.

Methods Patients with history of MIOL implantation were screened for the presence of ERM using spectral-domain optical
coherence tomography (SD-OCT) at postoperative 6 months. Ninety-one eyes with mild non-foveal involving ERM and history
of MIOL implantation were compared with 83 age-matched controls without ERM and history of MIOL implantation.
The visual acuity (corrected and uncorrected) and visual quality (contrast sensitivity, Strehl ratio, area ratio, and higherorder
aberrations; HOAs) of the eyes with mild non-foveal involving ERM were compared with the data of the age-matched
control group.

Results There was no difference in visual acuity between the groups at baseline and postoperative 6 months. The mild nonfoveal
involving ERM group showed significantly low contrast sensitivity at a visual angle of 4.0°, 2.5°, 1.0°, and 0.64°
under scotopic conditions (P = .048, P = .025, P = .003, and P = .02, respectively) and 4.0°, 1.0°, and 0.64° under photopic
conditions (P = .028, P = .002, and P = .001, respectively). The mean area ratio of the mild non-foveal involving ERM group
was 45.13 ± 10.93, which was significantly lower than that of the control group, which measured 50.34 ± 12.66 (P = .044).
Conclusion A mild non-foveal involving ERM has no effect on visual acuity, but it reduces visual quality in eyes with MIOL
implantation. A thorough screening using SD-OCT is warranted for this condition when considering MIOL implantation.
