Table 1.
Changes of visual acuity, internal higher-order aberrations (HOAs) and questionnaire scores before and after vitrectomy
| Time point at examination | BCVA | Internal HOAs (μm) | Questionnaire score |
|
|---|---|---|---|---|
| General vision (pts) | Severity of floaters (pts) | |||
| Case 1 | ||||
| Before vitrectomy | 20/16 | 1.699 | 6 | 3 |
| After virectomy | 20/16 | 0.125 | 7 | 1 |
| Case 2 | ||||
| Before vitrectomy | 20/20 | 1.310 | 5 | 4 |
| After virectomy | 20/13 | 0.238 | 8 | 1 |
| Case 3 | ||||
| Before vitrectomy | 20/33 | 0.819 | 3 | 4 |
| After virectomy | 20/33 | 0.188 | 6 | 0 |
Although best-corrected visual acuity (BCVA) did not change after vitrectomy in cases 1 and 3, an improvement in the internal HOAs concomitant with an improvement in questionnaire scores was observed. In case 2, we observed an improvement in the BCVA and questionnaire scores concomitant with decreased internal HOAs after the vitrectomy.
BCVA; best corrected visual acuity. HOA; higher-order aberration.
