WebAug 19, 2024 · We introduce optical coherence refraction tomography (OCRT), a method that uses OCT B-scans from multiple angles to simultaneously reconstruct an undistorted, isotropic, high-resolution image and estimate the RI distribution. In particular, the superior axial resolution of OCT is extended to the inferior lateral resolution to form an isotropic PSF. WebAug 28, 2024 · Autorefraction was + 14.37 DS / + 2.25 DC × 142. Biometry was repeated with the same biometer [Fig. 3] and demonstrated different axial lengths in both eyes: 21.67 mm in the right eye and 21.69 mm in the left eye. The patient subsequently underwent an intraocular lens exchange.
