“…Due to postoperative complications involving the crystalline lens, more than half of phakic patients who underwent vitrectomy for RRD repair subsequently needed cataract surgery within 1 year [5]. Thus, combined phacovitrectomy was encouraged for patients aged 50 or older due to the lower cost of surgery, reduced complications and better visual outcome [6][7][8][9]. In 10-17% of cases of RRD with macular involvement, it was impossible to measure the axial length (AL) using optic biometry (IOLMaster) because of the limitations of the machine, such as dense media opacity, poor fixation by the patients or the lack of an available machine [10][11][12].…”

Introduction: This study was performed to observe the potential refractive prediction error based on alternative A-scan ultrasound and fellow-eye biometry for phacovitrectomy in macula-off rhegmatogenous retinal detachment (RRD) eyes. Methods: Phakic macula-off RRD eyes without axial length (AL) measurements obtained using IOLMaster were included. Vitrectomy without lens extraction was performed for RRD repair.Preoperative AL was measured using alternative A-scan ultrasound (AL-US). Postoperative AL was obtained in eyes with silicone oil tamponade (AL-SO) and preoperative fellow-eye biometry (AL-FE) using IOLMaster. Other eyes that faced the same preoperative situation but underwent phacovitrectomy based on felloweye biometry were recruited as controls.Results: AL-US, AL-FE, and AL-SO were 25.39 ± 2.14 mm, 25.85 ± 2.16 mm and 26.08 ± 2.53 mm, respectively. The Bland-Altman agreement among AL-US, AL-FE and AL-SO was good (95.5%, 21/22 of cases were in the LoA). The mean IOL power calculated using AL-US (Power-US), AL-FE (Power-FE) and AL-SO (Power-SO) was 16.81 ± 7.19 D, 14.74 ± 6.95 D and 13.54 ± 8.32 D, respectively. The difference between AL-US and AL-SO was significant (P \ 0.05), while that between AL-FE and AL-SO was not (P [ 0.05). The difference between Power-US and Power-SO was significant (P \ 0.05), while that between Power-FE and Power-SO was not (P [ 0.05). Nine eyes underwent phacovitrectomy based on fellow-eye biometry and had a final postoperative myopic shift of 0.64 ± 0.78 D. Conclusions: Alternative A-scan ultrasound led to a significant difference in AL and a prediction error in IOL power, while fellow-eye biometry provided similar results to silicone oil-filled eyes after RRD repair.

Purpose To determine the incidence of clinically significant pseudophakic cystoid macular edema (CSPME) after phacoemulsification using the ‘bag-in-the-lens’ lens (BIL) implantation technique and to examine the influence of associated risk factors for clinically significant pseudophakic macular edema (CSPME), both ocular and systemic. Methods This retrospective study included 2419 first-operated eyes of 2419 adults who underwent phacoemulsification cataract surgery using the BIL implantation technique between January 2013 and December 2018 in the Antwerp University Hospital, Belgium. The significance of several risk factors (age, gender, previous history, intra- and postoperative complications) was examined by extraction of electronic medical files. Results The 3-month incidence of CSPME in the subgroup without risk factors was 0.00% (95% CI: 0.00 –NA). The 3-month incidence of CSPME in the subgroup with risk factors was 0.57% (95% CI 0.22–1.29%). The 3-month incidence of CSPME in the total population of 2419 patients was 0.29% (95% CI: 0.11–0.65%). The risk factors most significantly associated with CSPME included renal insufficiency (hazard ration [HR]: 5.42; 95% CI: 1.69–17.44; P = .014), exudative age-related macular degeneration (HR: 74.50, 95% CI: 25.75–215.6; P < .001) and retinal vein occlusion (HR: 22.48, 95% CI: 4.55–111.02; P = .005). Conclusions In the absence of risk factors, the incidence of CSPME was zero. We can conclude that Primary Posterior Continuous Curvilinear Capsulorhexis (PPCCC) does not increase the risk for CSPME. Non-inferiority of the BIL implantation regarding the development of CSPME, relative to the traditional ‘lens-in-the-bag’ (LIB) implantation, confirms that BIL is a safe surgical technique. This study also illustrates a previously undescribed risk factor for developing CSPME, namely renal insufficiency.

We observe the potential refractive error basing on alternative A-scan ultrasound and fellow-eye biometry for phacovitrectomy in phakic macula-off rhegmatogenous retinal detachment (RRD) eyes, when IOLMaster fails to obtain data. Vitrectomy without lens extraction was performed for RRD repair. Preoperative axial length was measured using alternative A-scan ultrasound (AL-US). Postoperative axial length in eyes with silicone oil tamponade (AL-SO) and fellow-eye biometry (AL-FE) were obtained using IOLMaster. AL-US, AL-FE and AL-SO were 25.39 ± 2.14 mm, 25.85 ± 2.16 mm and 26.08 ± 2.53 mm, respectively. The Bland-Altman agreements among AL-US, AL-FE and AL-SO were well (95.5%, 21/22 of cases were in LoA). The mean IOLs power calculated using AL-US (Power-US) was 16.81 ± 7.19 D, using AL-FE (Power-FE) was 14.74 ± 6.95 D, and using AL-SO (Power-SO) was 13.54 ± 8.32 D. The difference between AL-US and AL-SO was significant (P < 0.05), while that between AL-FE and AL-SO was not (P > 0.05). The difference between Power-US and Power-SO was significant (P < 0.05), while that between Power-FE and Power-SO was not (P > 0.05). It showed that the alternative A-scan ultrasound leads to significant differences in axial length and IOLs power prediction, while fellow-eye biometry provided similar measurements compared with those of silicone oil-filled eyes after RRD repair.

Bag-in-the-lens implantation helps avoid posterior synechiae of the iris after phacovitrectomy

Abstract: To compare the rate of occurrence of posterior synechiae of the iris (PSI) after phacovitrectomy between a group with Lens-In-the-Bag (LIB) implantation, i.e. implantation in the capsular bag and a group with Bag-In-the-Lens (BIL) implantation.
