“…[ 3 ] In addition, a silicone cannula also adds extra cost for patients in developing counties such as China. Siyal et al [ 7 ] introduced an approach for passively draining silicone oil through a 23-gauge vitrectomy system. However, it would be also very time consuming for the ROSO when the viscosity is high (e.g., 5700 centistokes).…”

To report and compare 2 modified approaches for the active removal of silicone oil (ROSO) with a 23-gauge transconjunctival vitrectomy system.This prospective single blinded study was conducted from January 2015 to December 2016. Eighty-nine eyes of 86 patients who underwent silicone oil removal were enrolled. Patients were randomly divided into either group A or B. In group A, the fluid–air exchange tube was connected to a 1 mL syringe with the plunger removed and the tip was dilated with a hemostat so that it fit into the cap of the 23-gauge cannula to form a seal for oil drainage. In group B, the tip of the syringe was closely attached to the cap of the 23-gauge cannula by a tube adaptor, which was salvaged from a used silicone oil inject and aspirate pack and sterilized. Main outcome measures were time required for silicone oil removal, silicone oil residual, intraoperative and postoperative complications including hypotony, bleeding, and retinal redetachment.The mean time required was 6.08 ± 0.31 minutes and 6.11 ± 0.31 minutes for groups A and B, respectively. No silicone oil residual, severe hypotony, recurrence of retinal detachment, or impairment of visual acuity were observed in either group. Conjunctival injection and hyperemia were slightly more severe in group A, but spontaneously resolved in 2 to 3 days.Both methods described in this paper were demonstrated to be safe, effective, and cost-effective for the ROSO. The syringe dilation method caused more severe conjuntival irritation, thus we suggest using the tube adaptor method for hospitals equipped with cold sterilization equipment.

Objectives: To compare the effectiveness of fluid-air exchange with silicone oil-fluid exchange in reducing the residual silicone oil (SO) droplets after the removal of SO. Methods: This was a prospective, quasi-experimental study conducted from October 2021 to February 2022 at Eye Unit-III, COAVS, Mayo Hospital, Lahore. Sixty-one patients with siliconized eyes underwent removal of SO with two different techniques and were divided into fluid-air exchange and oil-fluid exchange groups. To quantify the residual silicone droplets objectively, B-scan echographic images were analyzed within seven days of surgery. Silicone oil index (SOI) which is the amount of residual SO droplets/vitreal area in the images was calculated with the help of imagej software. Results: The residual SOI of the fluid-air exchange group (0.99 ± 1.76%) was significantly lower than the oil-fluid exchange group (3.25 ± 3.85%). The SOI is positively correlated with the duration of tamponade, preoperative intraocular- pressure and axial length. Persistent IOP elevation post-operatively was seen in 16.67% individuals in the fluid-air exchange group and 54.8% individuals in the oil-fluid exchange group. Conclusion: Fluid-air exchange group was found to be superior in reducing residual SO droplets than the oil-fluid exchange group. doi: https://doi.org/10.12669/pjms.39.2.6243 How to cite this: Rizwan A, Javaid RMM, Latif S, Sarwar MS, Khan AA.

Objective: Objective of our study was to determine accuracy of IOL Master and A scan acoustic biometry in silicon filled eyes in terms mean difference of axial length pre-operatively and mean post-operative refractive error Study design: Comparative cross sectional study Study settings and duration: Study was conducted at department of Ophthalmology (Eye Unit III) Mayo hospital Lahore (KEMU) from November 2019 to April 2020. Material and methods: WHO calculator was used for calculation of patient sample (N=34). Patients were randomly divide in two groups Group I underwent preoperative axial length (AXL) measurement by using IOL Master and by acoustic a-scan ultrasound in Siliconized mode. Results: Total 34 patients were included in study. There were 18(52.9%) male and 16(47.1%) female. Mean age of patients was 44.2±6.4 years. Patients undergone biometry with Master IOL showed better visual acuity (Log Mar) (0.25±0.7, 0.63±0.09, p=0.000), less post-operative refractive error (0.22±0.02, 0.72±0.17, p=0.000) as compared to those in which A scan acoustic biometry was done. A significant difference in post-operative axial length was reported (p=0.04) Conclusion: IOL master is more accurate and reliable method of IOL power calculation resulting in better visual outcomes and less post-operative refractive error as compared to A scan acoustic biometry in silicon filled eyes. Keywords: A scan Acoustic biometry, Axial length, IOL Master
