Influence of the dilution method on the intraocular duration of C3F8 in vitrectomy for macular hole: a randomized clinical trial.

Purpose: To compare the injection of small amounts of undiluted C3F8 with the traditional gas injection in vitrectomy for macular hole treatment.

Methods: This clinical trial included 26 individuals divided into two groups. Group 1 received an intravitreal injection of 0.

Use of axial length to estimate the vitreous chamber volume in pseudophakic.

Purpose: To develop an equation for estimating the vitreous chamber volume in pseudophakic patients based on the axial length of the eye.

Methods: A consecutive series of patients who underwent vitrectomy surgery for a macular hole or an epiretinal membrane were enrolled. The inclusion criteria were as follows: having pseudophakia, being older than 50 years, and having eyes with axial length ranging from 21 to 26 mm.

Effect of preoperative use of topical prednisolone acetate, ketorolac tromethamine, nepafenac and placebo, on the maintenance of intraoperative mydriasis during cataract surgery: a randomized trial.

Purpose: To compare the effects of preoperative use of topical anti-inflammatory prednisolone acetate, ketorolac tromethamine, nepafenac and placebo, on the maintenance of intraoperative mydriasis during cataract surgery.

Design: Randomized clinical trial.

Materials And Methods: This single-center, masked, randomized clinical study comprised 140 patients scheduled for cataract surgery.
