摘要
To compare the use of single‑pass four‑throw (SFT) and traditional double-pass two-throw knotting (DTT) techniques in pupilloplasty for traumatic mydriasis combined with lens dislocation, and to evaluate the learning curve between the two knotting techniques by wet lab.The eyes of 45 patients (45 eyes) were divided into two groups according to the knotting technique used: single‑pass four‑throw (22 eyes) or traditional double-pass-two-throw knotting (23 eyes). Combined phacoemulsification and pupilloplasty with pars plana vitrectomy were performed in traumatic mydriasis patients with lens dislocation. Preoperative and postoperative corrected distance visual acuity (CDVA), pupil diameter, intraocular pressure (IOP), pupilloplasty time, and complications were compared. Twenty ophthalmology residents were randomized to perform a pupilloplasty suturing exam with or without SFT knotting techniques in porcine eyes.All cases had a minimum follow‑up period of 6 months (range 6-12 months). There was no significant difference in the CDVA (P = 0.55), postoperative pupil diameter (P = 0.79), IOP (P > 0.05), anterior chamber exudate degree, and loosening or shedding of the line knot between the two groups. The duration of the pupilloplasty was 22.32 ± 4.58 min in the SFT group and 30.35 ± 5.55 min in the traditional group, which was a significant difference (P < 0.01). The residents in the SFT group had higher test scores and fewer surgical mistakes (P < 0.05).The SFT knotting technique has a similar treatment effect and safety as the traditional technique but requires a shorter time and is easier to perform in pupilloplasty surgery.
