(Summary description)"Primary" or "delayed"? IOL tilt and decentration evaluated by panoramic AS SS-OCT! Research recently published in <IJO> evaluated the tilt and decentration of intraocular lenses (IOLs) in eyes that underwent phacovitrectomy for macula-off rhegmatogenous retinal detachment (RRD) repair by using panoramic anterior segment (AS) swept source OCT. 63 patients with macula-off RRD who underwent phacovitrectomy were enrolled and divided into a primary implantation group and a delayed implantation group according to the time of IOL implantation. IOL tilt, measured as α angle—angle of the IOL axis (black line) and the pupillary axis (green line), and IOL decentration (red segment, distance between IOL center and the pupillary axis) were analyzed on the device (figure 1). Results showed that the absolute values of IOL tilt and decentration were greater in eyes with delayed IOL implantation than in eyes with primary implantation. Primary IOL implantation leads to a postoperative myopic shift, while in the delayed group, the extent of IOL tilt and decentration positively correlated with the time interval between phacovitrectomy and IOL implantation. A 100KHz speed full range swept source OCTA (#YAlkaid, TowardPi Medical) was used in this study to achieve panoramic AS OCT with 15mm scan depth, which makes it easy to visualize entire anterior segment from top of cornea to posterior lens capsule. All measurements are automatic assisted by AI technology on the device (figure 2). This research was authored by Dr. Qingchen Li from Shanghai Aier Eye Hospital, and Dr. Rui Liu from Shanghai Municipal Hospital of Traditional Chinese Medicine. Special appreciation for the suggestions and assistance given by Dr. Jian Zhou. Link to original text: https://lnkd.in/gqD4nePf
