AB  - OBJECTIVE: To investigate the refractive change and optical biometry dynamics 
      after 25-gauge vitrectomy without gas tamponade for macular pathology in 
      pseudophakic eyes. DESIGN: A prospective observational case series. PARTICIPANTS: 
      Patients with pseudophakic eyes who were scheduled for vitrectomy owing to 
      macular pathology by an experienced surgeon (T.S.) at the Hayashi Eye Hospital 
      between March 2019 and February 2020. METHODS: The primary endpoint was the 
      change in manifest refraction spherical equivalent (MRSE) between baseline 
      (preoperatively) and 3 months postoperatively. The secondary endpoint was the 
      change in optical biometry parameters obtained by swept-source optical coherence 
      tomography-based biometers between baseline and 3 months postoperatively. Optical 
      biometry parameters included corneal curvature and axial length, evaluated by the 
      IOLMaster 700, and intraocular lens position-that is, lens decentration, lens 
      tilt, and aqueous depth (AQD)-evaluated by the CASIA2. RESULTS: Thirty-four eyes 
      of 34 patients were enrolled. The mean MRSE values at baseline and 3 months 
      postoperatively were -0.70 +/- 1.21 diopter (D) and -0.82 +/- 1.27 D, respectively, 
      showing a significant myopic shift of -0.12 +/- 0.41 D postoperatively (p = 0.043). 
      There was no significant difference between the pre- and postoperative values of 
      the optical biometry parameters, except for the AQD (4.28 +/- 0.34 mm vs 4.27 +/- 
      0.34 mm; p = 0.019). CONCLUSIONS: The results suggest that replacing the vitreous 
      by the aqueous during vitrectomy induces an average myopic shift of -0.12 D.
