“…The 23-G vitrectomy allows for increased comfort, faster healing time, reduced corneal astigmatism, shorter surgical time, rapid postoperative and visual recoveries, less inflammation and less disruption to the conjunctiva than with 20-gauge procedures [ 26 , 27 ]. The smaller port size of the instruments increases the ability to remove vitreous with very little traction or to remove epiretinal membranes without risking incarceration of the retina in the port.…”

BackgroundTo evaluate the morpho-functional outcomes and safety of transconjuctival 23-gauge pars plana vitrectomy(PPV) for removal of intraocular foreign bodies (IOFBs).MethodsA retrospective study of 36 consecutive cases (mean age; 34,2 ± 10,9 years (between 15 and 60), 27 M,9 F) of 23-G PPV for the removal of IOFBs during the period of April 2009 and December 2011 and followed 9,4 ± 6,4(2–27) months were conducted. Visual outcomes, slit lamp biomicroscopy, intraocular pressure (IOP), and posterior segment visualization by indirect ophthalmoscopy, A-B mode ultrasonography, and computed orbital tomography were performed for all cases. Main outcomes including anatomic and visual outcomes, and both intraoperative and postoperative complications were recorded.ResultsOf the 36 cases available for the study, the IOFBs (size range, 3 to 12 mm) could be removed in all eyes. Mean preoperative LogMAR BCVA was 1.44 ± 138 (range, 1.00 to 0.00) and mean postoperative LogMAR BCVA at final visit was 0,78 ± 0,98 (range, 1.00 to 0.00). (P = 0,007) Anatomic success was obtained in 97.2 % of eyes. 16 patients needed primary wound repair due to the leakage in insertion sites before the PPV, however remaining 20 cases were not. Fibrin reaction was seen in 8 (22.2 %) patients in early postoperative period, intraocular pressure elevation was detected in 12 (33.3 %) patients in which the silicone oil was used as an intravitreal tamponade, one patient with silicone oil tamponade developed band keratopathy and phthisis bulbi.Conclusions23-Gauge PPV is a feasible, effective approach in the surgical management of the patients with posterior segment intraocular foreign bodies.

“…A larger and longer cataract surgical incision destroyed the structure of the corneal dome more severely, leading to a more signi cant postoperative corneal astigmatism [14]. Translimbal incision more likely causes corneal astigmatism than transscleral tunnel incision [15], and tighter sutures caused noticeable changes in corneal astigmatism [16].…”

Background Cataracts are commonly seen during the diagnosis of rhegmatogenous retinal detachment (RRD) or occur following its surgical management. Refractive changes following combined phacoemulsification and vitrectomy (phacovitrectomy) can affect the quality of vision. This study aimed to evaluate the refractive changes following vitrectomy versus phacovitrectomy in patients with RRD. Methods A total of 96 patients who underwent retinal surgery for RRD in one eye, between August 2016 and January 2018, were enrolled and divided into three groups. In 18 eyes, 23-gauge transconjunctival sutureless vitrectomy (23G TSV) was performed (group A); 25G TSV was performed in 49 eyes (group B), and phacovitrectomy with 25G TSV was performed in 29 eyes (group C). Silicone oil was injected after the surgery in all three groups. Anterior and posterior corneal astigmatism, axial length (AL), and anterior chamber depth (ACD) were measured at baseline and postoperatively at 1 week, 1 month, and 3 months. Results Anterior and posterior corneal astigmatism did not change, and AL continued to increase for 3 months after surgery, whereas ACD decreased postoperatively but quickly returned to baseline in groups A and B. In group C, anterior and posterior corneal astigmatism, AL, and ACD increased postoperatively, and corneal astigmatism returned to baseline by 3 months, but AL and ACD continued to increase for 3 months. Conclusion Vitrectomy alone does not affect anterior or posterior corneal astigmatism. Following vitrectomy, the AL increases, while the ACD decreases transiently. When vitrectomy is combined with phacoemulsification for cataract removal, the anterior and posterior corneal astigmatism increases transiently, while AL and ACD are enlarged for several months following surgery.

“…Over the past decade, micro-incision vitrectomy surgeries using either 23-or 25gauge systems have increased in popularity among surgeons [4]- [11]. The advantages of small-incision PPV over the traditional 20-gauge approach include a reduction in surgical trauma, self-sealing wounds, decreased post-operative inflammation and faster visual recovery [12] [13].…”

Background: We sought to verify the efficacy and safety of transconjunctival 23gauge pars plana vitrectomy (PPV) alone by our bimanual technique for the removal of dense posteriorly dislocated crystalline lens. Methods: A retrospective, noncomparative, interventional study of 31 consecutive cases of patients who underwent 23-gauge PPV alone for the removal of dense posteriorly dislocated crystalline lens following complicated cataract surgeries using our bimanual technique was conducted. The main outcomes measured included best-corrected visual acuity (BCVA), preoperative intraocular pressure (IOP), postoperative IOP and postoperative complications. Results: In all 31 cases included in this study, those dense posteriorly dislocated crystalline lenses were successfully removed. The enrolled patients consisted of 17 males and 14 females with a mean age of (75.84 ± 6.17) years (range 59 -90). The mean follow-up length was (7.61 ± 1.87) months with a range of 6 months to 1 year. The mean preoperative BCVA was 0.22 ± 0.11 logMAR system, and the postoperative BCVA was 0.33 ± 0.07 logMAR system after 6 months of follow-up. The mean operative time was 46.32 ± 4.80 minutes with a range of 38.00 to 57.00 minutes. All of the conjunctival incisions self-closed within the first week with no wound leakage or hemorrhage. The postoperative complications were relatively rare. Conclusions: The removal of dense posteriorly dislocated crystalline lens might be a challenge for micro-incision vitrectomy. Our bimanual technique was proved to be an effective and safe method for those particular dense lenses using 23-gauge alone.
