Refractive Outcomes of Phacovitrectomy in Retinal Detachment Compared to Phacoemulsification Alone Using Swept-Source OCT Biometry.

Background And Objective: To assess the refractive outcomes in patients who underwent combined phacovitrectomy for retinal detachment compared to phacoemulsification and intraocular lens (IOL) implant utilizing newer swept-source optical-coherence-tomography (SS-OCT) biometry and determine the requirement of an adjustment factor for superior predicted refractive outcomes.

Patients And Methods: Retrospective study of 95 eyes: 52 eyes that underwent phacovitrectomy and 43 eyes with phacoemulsification only that served as the control group. Mean refractive error (ME) and mean absolute error (MAE) were used to compare the groups.

ASSESSING REFRACTIVE OUTCOMES AND ACCURACY OF BIOMETRY IN PHACOVITRECTOMY AND SEQUENTIAL OPERATIONS IN PATIENTS WITH RETINAL DETACHMENT COMPARED WITH ROUTINE CATARACT SURGERY.

Purpose: To compare refractive outcomes and accuracy of modern optical biometry, swept-source optical coherence tomography, ultrasound biometry, and effect of the macula status in rhegmatogenous retinal detachment managed with either combined phacovitrectomy or sequential vitrectomy and cataract surgery compared with a control, phacoemulsification alone.

Methods: Retrospective, comparative, consecutive study of 154 eyes; Group 1 underwent phacovitrectomy (n: 70), Group 2 underwent vitrectomy with subsequent cataract surgery (n: 41), and Group 3 underwent cataract surgery alone (n: 43).

Results: No difference in the mean absolute error was found between Group 2 (0.

Preliminary measurement of gas concentrations of perfluropropane using an analytical weighing balance.

We describe the use of an analytical weighing balance of measurement accuracy 0.00001g for determination of concentrations of perfluropropane (C3F8) gas used in ophthalmic surgical vitrectomy procedures. A range of test eyes corresponding to an eye volume of 6.

Efficacy of autologous platelets in macular hole surgery.

The introduction of optical coherence tomography has allowed accurate measurement of the size of macular holes. A retrospective consecutive review was performed of 21 patients undergoing macular hole repair with vitrectomy, gas tamponade, and autologous platelet injection and we assessed the effect of macular hole parameters on anatomic and functional outcomes. We looked at the demographic features, final visual outcome, and anatomical closure.

Secondary angle-closure glaucoma due to posterior synechiae formation following phacovitrectomy.

Iris posterior synechiae formation after phacovitrectomy is usually regarded as a trivial problem. We report a case of secondary angle-closure glaucoma due to 360°PS 5 years after a phacovitrectomy for recurrent vitreous haemorrhage secondary to diabetic retinopathy. To our knowledge this is the first such reported case of this potentially sight-threatening complication of phacovitrectomy.

Stabilization of anterior chamber depth during phacoemulsification cataract surgery in vitrectomized eyes.

Abnormal fluctuations in anterior chamber (AC) depth including deepening and mydriasis with paradoxical shallowing and miosis have been described during phacoemulsification cataract surgery in previously vitrectomized eyes. Contributory factors include zonular laxity and reduction of vitreous volume. This report describes a technique to stabilize AC depth and allow safer sculpting and removal of lens matter.
