Reverse order method for teaching cataract surgery to residents.

Objective: To implement a method to train residents in the performance of phacoemulsification surgery, with the steps completed in reverse chronological order and with the easiest step being undertaken first.

Methods And Analysis: We created a method for training ophthalmology residents in which we taught phacoemulsification surgery in a series of steps learnt in reverse order. Each resident advanced through the teaching modules only after being approved in the final step and then progressed to the complete performance of surgeries.

Ultrasound Biomicroscopy Comparison of Ab Interno and Ab Externo Intraocular Lens Scleral Fixation.

Purpose. To compare ab interno and ab externo scleral fixation of posterior chamber intraocular lenses (PCIOL) using ultrasound biomicroscopy (UBM). Methods.

Visco-fracture technique for soft lens cataract removal.

Unlabelled: We describe a visco-fracture technique for soft nucleus phacoemulsification. Following continuous curvilinear capsulorhexis, cortical cleavage hydrodissection, and hydrodelineation, an ophthalmic viscosurgical device (OVD) is delivered into the eye through a hydrodissection cannula. A small amount of pressure is used to introduce the cannula into the nucleus.

[Reliability of predictable postoperative visual acuity of cataracts as measured by Heine Lambda 100 retinometer preoperatively].

Purpose: To assess the relationship between potential visual acuity obtained before cataract surgery using Heine Lambda 100 retinometer with best corrected visual acuity 3 months postoperatively, as well as its correlation with the morphological pattern of the dominant cataract and the intensity of nuclear opacification.

Methods: Prospective study executed in the Ophthalmology Hospital Laser Vision in Santos of 121 eyes of 70 patients who underwent cataract surgery (phacoemulsification with intraocular lens implantation), from April to July, 2009. In the preoperative period, Heine retinometer test was performed under mydriasis and its results were compared to postoperative best corrected visual acuity three months after surgery and correlated with the morphological classification of cataracts, being considered a satisfactory result those who did not vary more than two lines in Snellen chart.

[Effect of honey and autologous serum on corneal epithelial healing in rabbits].

Purpose: To evaluate the efficacy of pure honey and 20% autologous serum and BSS in corneal epithelial healing in rabbits after 48 hours.

Methods: All solutions were applied after an epithelial removal of 13-millimeters diameter area. Areas of epithelial healing were studied at 12, 24 and 48 hours.
