“…[6] evaluated the ACD by AS-OCT and found a signi cant decrease until 9 months after SB surgery. Similarly, the ACD decrease after scleral encircling has been attributed to the anterior rotation of the ciliary body associated with surgicallyinduced ciliary congestion and subsequent forward shift of the lens-iris diaphragm [17]. However, in our study, there was no signi cant decrease of the CACD in the operated eyes.…”

Background: This study was to evaluate anterior segment parameter changes following scleral buckling (SB) surgery for rhegmatogenous retinal detachment (RRD) using the Pentacam Scheimpflug system.Methods: Twenty-eight phakic eyes of 28 patients who underwent SB surgery for RDD were included. The anterior chamber volume (ACV), central anterior chamber depth (CACD), mean anterior chamber angle (ACA) and ACA in a specific position (buckle quadrant), and central corneal thickness (CCT) were evaluated preoperatively and at 1 day, 1 week, and 1 and 3 months postoperatively by an anterior Pentacam Scheimpflug method. Results: The ACV parameters were significantly decreased compared with preoperative levels at 1 day, 1 week, and 1 and 3 months after SB surgery (P<0.05). The mean intraocular pressure (IOP) at 1 day was significantly higher than the preoperative level, but no subsequent significant difference was noted between the preoperative IOP and that at 1 week and 1 and 3 months postoperatively (P>0.05). The CCT at 1 day after surgery increased significantly and subsequently returned to the normal level postoperatively at 1 week and remained stable until 3 months (P>0.05). The degree of postoperative CACD displayed no significant change in the different quadrants. There was a significant increase in the ACA of the buckle quadrants at 1 day, 1 week, and 1 month after surgery (P<0.05), returning to the normal level at 3 months.Conclusion: The changes of anterior chamber parameters after SB can be demonstrated by Pentacam both objectively and quantitatively. The ACV and CCT changes were mild and resumed their preoperative parameters after 1week, while the increase of the ACA at the buckle quadrant returned to normal after 3 months.

“…Although ACD was still significantly deeper and AL was longer at the final follow-up visit than at baseline, despite having a myopic shift, SER revealed no significant difference from baseline values in our participants. In contrast, Albanese et al [22] found a significant myopic shift at the last follow-up in operated eyes compared to baseline refraction. Despite the differences in the phakic status of the included eyes and the study design, using an absorbable suture to tighten the encircling band resulted in the reduced significance of the myopic shift in our study.…”

“…Albanese et al [22] found significant differences in AL, ACD, and SER in phakic eyes treated with SB for primary macula-on RRD compared with fellow phakic eyes at a mean (SD) follow-up duration of 50.9 (21.9) months. Operated eyes experienced -1.35 (0.57) D myopic shift, 0.83 (0.23) mm increase in mean (SD) AL, and 0.09 (0.18) mm shallowing in mean (SD) ACD at the last follow-up.…”

Background: Rhegmatogenous retinal detachment (RRD) is a separation of the neurosensory retina from the retinal pigment epithelium as a result of liquid vitreous passing through a retinal break. Scleral buckling surgery (SB) is a conventional treatment for RRD. In SB, a silicon explant is used to indent the sclera, reduce vitreous traction, and close the retinal break, and an encircling band is used circumferentially, leading to myopia. This study aimed to evaluate the functional and biometric outcomes after SB with absorbable band-tightening sutures in patients with pseudophakic RRD. Methods: In this prospective interventional study, we included pseudophakic eyes with RRD treated surgically with SB and a temporary encircling band using a 6-0 absorbable Vicryl suture to tighten the band, instead of conventional permanent suture tightening. Anterior chamber depth (ACD), axial length (AL), intraocular pressure (IOP), spherical equivalent refractive error (SER), and best-corrected distance visual acuity (BCDVA) were measured preoperatively and at 1 day, 2 weeks, 3 months, and 6 months postoperatively. Results: We included 30 eyes of 30 patients with a mean (standard deviation [SD]) age of 66.1 (10.5) years who underwent SB with an absorbable band-tightening suture for pseudophakic RRD. Significant increases in AL and ACD were observed at 2 weeks after surgery, with a significant decline in values thereafter; however, at the 6-month follow-up, the values were significantly higher than those at baseline (all P < 0.05). Based on the Vicryl tension and its hydrolysis, mean (SD) SER at 2 weeks postoperatively was significantly more myopic than at baseline (-5.8 [1.6] D versus +1.3 [1.8] D). However, the mean (SD) SER decreased significantly throughout the 6-month follow-up (all P < 0.05), and it reached -1.8 (0.9) D, which was comparable with the mean baseline SER (P = 0.140). The participants experienced significant improvement in BCDVA throughout the follow-up period (all P < 0.05). Conclusions: Using an absorbable suture to tighten the encircling band in patients with pseudophakic RRD can reduce postoperative myopia without adversely affecting the anatomical or functional outcomes. Future comparative studies with larger sample sizes and longer postoperative follow-up are needed to verify these findings.

“…28 Scleral buckling surgery alters the ocular structure, resulting in a longer AL and shallower ACD compared with preoperative measurements. [29][30][31] These changes in turn affect the IOL calculation, but the prediction accuracy for such patients remains largely unknown. Lamson et al observed a myopic bias (À0.159 D) in eyes with previous scleral buckling, whereas the difference was not statistically significant when compared with the total population.…”

Purpose: To determine the optimal intraocular lens (IOL) calculation formula for vitrectomized eyes with diverse surgical and biometric characteristics. Setting: Zhongshan Ophthalmic Center, Sun Yat-sen University, China. Design: Retrospective consecutive case-series study. Methods: This study included 974 vitrectomized eyes (974 patients) scheduled for phacoemulsification with IOL implantation. Eleven formulas were evaluated: Barrett Universal II(BUII), Emmetropia Verifying Optical, Hoffer-QST, Kane, Ladas Super Formula, Pearl-DGS, Radial Basis Function (RBF), Haigis, HofferQ, Holladay1, and SRK/T. Risk factors for prediction error (PE) exceeding 1D were determined using multiple logistic regression. Subgroup analyses were performed based on surgical history and biometric parameters. Results: The risk of hyperopic PE (>1D) was higher in patients with silicone oil tamponade (odds ratio [OR], 1.82) and longer axial length (AL) (OR, 1.55), while patients with previous scleral buckling (OR, 2.43) or ciliary sulcus IOL implantation (OR, 6.65) were more susceptible to myopic PE (<-1D). The Kane formula had the highest overall prediction accuracy, and also the best in silicone oil-filled eyes and the flat cornea subgroup. The BUII and RBF displayed the optimal performance in eyes with previous scleral buckle and steep cornea, respectively. In eyes with an AL ≥ 26mm, the Holladay1 with the nonlinear version of the Wang-Koch AL adjustment (Holladay1-WKn) showed the lowest absolute PE and highest percentage within ± 1.0D of PE. Conclusions: The Kane achieved the highest overall prediction accuracy in vitrectomized eyes. The optimal formula for eyes with previous scleral buckle, steep cornea, or long AL was BUII, RBF, and Holladay1-WKn, respectively.
