“…Preoperative AL, ACD and LT of RRD eyes were measured using an IOLMaster 700 (Carl Zeiss Meditec Ltd., Jena, Germany) as formerly described [ 14 , 15 ]. According to Kunavisarut [ 13 ] and El-Khayat [ 16 ], only measurements from an IOLMaster with a signal-to-noise ratio (SNR) value greater than 2 were included. Postoperative measurements were also obtained using the IOLMaster 700 with silicone oil-filled phakic eyes program before silicone oil removal.…”

Background: To observe the changes in ocular biometric measurements after vitrectomy with silicone oil tamponade for rhegmatogenous retinal detachment (RRD) repair. Methods: Sixty-three phakic, macula-off RRD eyes underwent vitrectomy with silicone oil tamponade but not lens extraction were included in this retrospective study. Measurements of axial length (AL), anterior chamber depth (ACD), lens thickness (LT) using the new Zeiss IOLMaster 700 and derivative lens position (LP), relative lens position (RLP) and lens-retina distance (LRD) were compared and analyzed between preoperative and postoperative in phakic, macula-off eyes with RRD.

“…As the advances emerging in microsurgical instrumentation on small-gauge vitrectomy, combined surgery has, therefore, become a popular procedure in treating RRD [5][6][7] . A high level of consistency of AL measured before and after PPV has been shown in both macula-sparing RRD cases [8] and macula-off RRD cases [1,2] . In RRD cases treated by combined surgery, selection of the IOL power using AL data measured before PPV is reported to result in a small biometric error and a small myopic shift that is within the tolerable range in most cases [9] .…”

“…Alternatively, it has been reported intraocular lens calculations using fellow-eye biometry for phacovitrectomy for macula off rhegmatogenous retinal detachments are accurate and better than those from same-eye biometry [2] . It was found in our study, the difference of AL between the affected eye and the fellow eye was greater before PPV than that before SOR in patients with RRD-CD.…”

“…The accuracy of the measurement of AL can be affected by several factors. High retinal detachment in the upright position [1] , macula-off status [1,2] and low IOP [3,4] may cause underestimation of AL.…”

BACKGROUND The precise pre-operative measurements of axial length (AL) are essential for calculating intraocular lens power in cases undertaking pars plana vitrectomy (PPV) combined with cataract surgery. The changes in AL after PPV for rhegmatogenous retinal detachment (RRD) combined with choroidal detachment (CD) has not been reported. Here, we studied the postoperative AL changes in patients with RRD combined with CD (RRD-CD) and compared the changes in patients with RRD and tractional retinal detachment (TRD). METHODS In this retrospective cohort study, medical records of 129 patients who received PPV combined with silicone oil tamponade from January 2015 to December 2018 were reviewed. Patients included were divided into three groups, RRD-CD, RRD, and TRD. All patients had received AL measurements before PPV and before silicone oil removal (SOR). The changes in AL of three groups before PPV and before SOR were compared. The potential factors related to AL changes were analyzed. RESULTS The number of patients included in RRD-CD, RRD, TRD groups were 41, 43, and 45, respectively. In RRD-CD group, AL measured before SOR was longer than that measured before PPV with a median of 1.01 [0.37,1.79] mm (p = 0.02). There was no such significant difference in RRD group (0.15 [0.04, 0.42] mm, p = 0.58) or TRD group (0.07[-0.03,0.15] mm, p = 0.53). The amplitude of AL changes in RRD-CD group was greater than that in RRD group (p < 0.001) and that in TRD group (p < 0.001). AL increased 0.06 mm (0.06, R2 = 0.11, p = 0.03) in RRD-CD group and 0.02 mm (0.02, R2 = 0.11, p = 0.01) in RRD group when the IOP before SOR was 1 mmHg higher than that before PPV. After adjusting the effect of the factors as the presence of pathological myopia (p = 0.45), IOP before PPV (p = 0.86), sustained elevation of IOP in post-PPV follow up (p = 0.51), AL in RRD-CD group was 11.42 times (3.54, 46.80) more likely to increase for more than 1 mm compared to that in RRD group (p < 0.001, AIC = 86.15). CONCLUSION Patients with RRD-CD are very likely to have postoperative elongation of AL. The primary IOL implantation using pre-operative AL data may cause significant refractive error in combined surgery in patients with RRD-CD.
