The role of mitomycin C and porcine extracellular matrix in phacotrabeculectomy.

Purpose: To compare between mitomycin C alone, porcine extracellular matrix alone, and combined low dose mitomycin C with porcine extracellular matrix in term of efficacy and safety in phaco-trabeculectomy surgery.

Study Design: Prospective comparative.

Methods: Sixty eyes of 60 patients complaining of primary open angle glaucoma and cataract, undergoing phaco-trabeculectomy, were distributed into three groups: group I: surgery was augmented with mitomycin C, group II with porcine extracellular matrix, and group III with porcine extracellular matrix combined with low dose mitomycin C.

Subjective Perception Of Trifocal IOL Performance, Including Toric Models.

Purpose: To study the patients' perception of trifocal IOL (Panoptix™) performance.

Patients And Methods: 60 eyes of 35 were implanted with trifocal IOL. Refractive (sphere - S, cylinder - Cyl and spherical equivalent - SE, all in D) and visual (distance uncorrected - VAsc, distance corrected - VAcc, intermediate - IntVA, near uncorrected - NVAsc and distance corrected near - NVAcc, all in LogMAR) results were recorded.

Effect of D-Panthenol on Corneal Epithelial Healing after Surface Laser Ablation.

Purpose: To study the effect of D-panthenol (provitamin B5) on corneal epithelial healing, in cases of surface laser ablation. : 45 eyes, of 45 patients undergoing laser surface ablation, received D-panthenol 2% in one eye and artificial tear drops of similar composition not containing D-panthenol in the other eye, postoperatively, for 2 months. Patients were examined daily for 3 days after the procedure.

Quality of Vision after Deep Anterior Lamellar Keratoplasty (Fluid Dissection) Compared to Penetrating Keratoplasty for the Treatment of Keratoconus.

Purpose: To compare the visual quality of patients with keratoconus who underwent penetrating keratoplasty (PKP) or deep anterior lamellar keratoplasty (DALK) with fluid dissection.

Design: Cross-sectional, observational study.

Methods: Twelve eyes that underwent PKP (PKP group) were compared to 24 eyes that underwent DALK (DALK group) after complete removal of sutures and stability of refraction.

Optical and topographic changes in keratoconus after implantation of Ferrara intracorneal ring segments.

Purpose: To assess the morphological, optical, and visual properties of the cornea before and after implantation of Ferrara intracorneal ring segments (ICRS) and compare them to normal values.

Methods: Thirty-seven keratoconic eyes were implanted with Ferrara ICRS and compared pre- and postoperatively with 38 non-keratoconic (normal) eyes. Examinations were performed using the NIDEK Optical Path Difference (OPD)-Scan II and analyzed using OPD-Station software.

Visual and optical performance before and after rotation of a misaligned STAAR Toric Implantable Collamer Lens.

Purpose: To document the use of the NIDEK OPD-Scan II/Station as a monitoring tool and clinical aid in the evaluation and re-rotation of a misaligned STAAR Toric Implantable Collamer Lens (TICL).

Methods: A 22-year-old man underwent bilateral TICL implantation. Emmetropia was achieved in the left eye after TICL implantation; however, the right eye showed residual compound myopic astigmatism.
