“…In our investigation using SS-OCT, the ACD showed no significant differences pre-or postoperatively between phacovitrectomized eyes and their partner eyes operated for cataract alone. Our findings agree with two recent investigations using the CASIA2 to measure ACD (Sato et al 2020;Shiraki et al 2020). Another study using the IOLMaster 700, however, found an increase in ACD after phacovitrectomy compared to cataract surgery, even though the distance between the anterior surface of the cornea and the IOL had to be remeasured manually in some cases due to inaccurate readings ( Vander Mijnsbrugge et al 2018).…”

“…Similarly, to ACD, we found no differences in the postoperative refractive error between phacovitrectomized eyes and their partner eyes operated for cataract alone. This finding agrees with three investigations, but inconsistent with three other previous studies that found a myopic shift after combined phacovitrectomy without air/gas tamponade (Falkner-Radler et al 2008;Manvikar et al 2009;Frings et al 2015;Sato et al 2020;Shiraki et al 2020;Tranos et al 2020). Tranos et al recently compared combined to sequential (vitrectomy followed by cataract surgery) phacovitrectomy and reported a greater myopic shift in the combined group.…”

“…Intraocular lens (IOL) power calculation depends on total corneal power, axial eye length as well as the postoperative IOL position and is essential for the prediction of the postoperative refraction and therefore patient satisfaction (Norrby 2008;Norrby et al 2017). Studies have investigated whether phacovitrectomy influences the IOL position and therefore the postoperative refractive outcome compared to phacoemulsification alone, reporting inconsistent findings (Falkner-Radler et al 2008;Manvikar et al 2009;Frings et al 2015;Vander Mijnsbrugge et al 2018;Sato et al 2020;Shiraki et al 2020;Tranos et al 2020). These inconsistencies may be caused by multiple factors including differences in study design (retrospective versus prospective with/without a control group), inclusion criteria (vitreoretinal conditions requiring air/gas versus fluid tamponades), operation techniques (core versus complete vitrectomy, 20-gauge versus 23-gauge vitrectomy and smaller) and IOL type.…”

Purpose To compare phacoemulsification versus phacovitrectomy regarding postoperative intraocular lens (IOL) shift and refraction. Methods This prospective bilateral comparison study included 40 eyes of 20 patients. Inclusion criteria were combined phacovitrectomy without gas/air tamponade in one eye and cataract surgery in the contralateral eye with implantation of the same IOL. Postoperative anterior chamber depth (ACD) was compared between both groups 1–5 hr, 1 day and 8 weeks after surgery. Postoperative refraction was compared after 8 weeks using the Holladay I, HofferQ, SRK/T, Haigis and Barrett formulae. Results There were no intergroup differences in ACD (8 weeks: 0.02 mm absolute difference, SD 0.22, range −0.36 to 0.65, p = 0.401), mean absolute refractive error (8 weeks: Holladay I p = 0.452; HofferQ p = 0.475; SRK/T p = 0.498; Haigis p = 0.869; and Barrett p = 0.352) or percentages within the 0.5 D and 1.0 D range at any time‐point. All formulae were optimized for the phacovitrectomy and the cataract groups. There was no correlation of macular thickness change and refractive error (cataract group r2 = −0.13, p = 0.58; phacovitrectomy group r2 = −0.10, p = 0.68). Conclusion Combined phacovitrectomy without air/ gas tamponade caused neither ACD displacement nor refractive shifts compared to phacoemulsification alone. Surgically induced macular thickness change had no significant influence on postoperative refraction in this study. All five IOL formulae showed comparable postoperative refractive outcomes.

“…On the other hand, other studies found no myopic shift in phacovitrectomy cases. 9 , 10 In a review study focused on this issue, there was no consensus regarding the post-operative ACD and ELP following phacovitrectomy. 11 The only consistent result of most of the studies reviewed was the small myopic shift observed with combined surgery – which has not been fully explained.…”

To investigate the effect of phacovitrectomy on the post-operative anterior chamber depth (ACD) and refractive outcomes, and to analyze the potential differences between vitreous filling with BSS, air and gas. Methods: Patients who underwent phacovitrectomy were included in this study and invited for repeated post-operative examination including refraction and biometry at least 3 months after the surgery. Data retrieved included demographic information, indication for phacovitrectomy, surgical details, type of vitreous filling (BSS, air or gas), pre-operative and postoperative biometric data including K-readings, axial length (AL), and ACD, as well as spherical equivalent (SE) values of the target and final refraction. Results: Forty-three eyes of 43 patients were included in this study, including 10 eyes filled with BSS, 18 with air and 15 with gas. The mean difference between the final measured spherical equivalent (SE) and the SE of the intended target refraction was 0.61±0.68 D (p = 0.019). Only 58.1% of eyes had a final SE within ±0.5D of the target refraction. Following surgery, AL remained unchanged, while mean pre-operative ACD increased significantly from 3.11±0.34 mm to 4.77±0.47 mm (p < 0.001). There was no difference in refractive error between the vitreous fillings and no correlation with AL or ACD. Conclusions: Phacovitrectomy is associated with lower accuracy of post-operative refraction compared to cataract surgery. This may be attributed to a significant change in ACD, influencing the effective lens position of the IOL, and may require adjustment of the preoperative calculations.
