Subjective and objective clinical outcomes of a new trifocal toric intraocular lens and effect of femtosecond laser cataract surgery.

Purpose: To evaluate the clinical outcomes and quality of life following implantation of PanOptix toric intraocular lens (IOL) and to compare the outcomes following femtosecond laser assisted cataract surgery (FLACS) and standard cataract surgery (SCS).

Methods: This comparative retrospective study included 79 eyes of 55 patients underwent cataract or refractive lens exchange surgery between April 2017 and January 2020 in Bayindir Hospital and Kaskaloglu Eye Hospital. Corneal (CA) and refractive astigmatism (RA), uncorrected visual acuities for distant, intermediate, and near (UDVA, UIVA, and UNVA), low contrast distance visual acuity, rotational stability, defocus curves, photopic and mesopic contrast sensitivity (CS), visual function-14 (VF-14) test, presence of dysphotopsia, and need for spectacles were evaluated at postoperative third month.

The novel haptic-twist method for a sutureless double-needle intrascleral haptic fixation technique.

Purpose: Description of a novel modified technique known as haptic-twist method for placing a trailing haptic into a 27 G needle during double-needle intrascleral haptic fixation (Yamane technique) in the absence and/or inadequacy of capsular support.

Methods: The trailing haptic was threaded into the needle lumen using a haptic-twist method in 12 eyes of 11 patients with aphakia. The haptic was grasped by a forceps 2-3 mm from the tip, while the forceps was rotated by 180° counter-clockwise around its own axis.

INTRAVITREAL NEEDLE TECHNIQUE FOR INTRASCLERAL HAPTIC FIXATION OF POSTERIORLY DISLOCATED THREE-PIECE INTRAOCULAR LENSES.

Purpose: Double-needle intrascleral haptic fixation (Yamane) technique is a minimally invasive method for posterior chamber intraocular lens (IOL) fixation in the setting of absent or inadequate capsule support. A modified intravitreal needle technique is herein described for the management of three piece IOLs which are dislocated into the vitreous cavity.

Methods: In this technique, after completing pars plana vitrectomy, under the noncontact ophthalmomicroscope, the haptic of the dislocated IOL is docked directly in the vitreous cavity into a 27-G needle which is inserted through a transconjunctival tunneled scleral incision 2 mm.

Visual and refractive outcomes, spectacle independence, and visual disturbances after cataract or refractive lens exchange surgery: Comparison of 2 trifocal intraocular lenses.

Purpose: To compare the clinical performance of a hydrophobic (AcrySof PanOptix) and a hydrophilic (AT LISA tri 839MP) diffractive trifocal intraocular lens (IOL).

Setting: Kaskaloglu Eye Hospital, Izmir, Turkey.

Design: Prospective case series.

Vitreoretinal Interface Characteristics in Eyes with Idiopathic Macular Holes: Qualitative and Quantitative Analysis.

Objectives: To determine the qualitative and quantitative vitreoretinal interface characteristics with spectral domain optical coherence tomography (SD-OCT) in eyes with macular hole (MH) and investigate their relation with best corrected visual acuity (BCVA) and MH duration.

Materials And Methods: Sixty-one eyes of 46 consecutive patients diagnosed with idiopathic MH were included in the study. The mean age of the patients was 66.

Comparison of hybrid and cross fragmentation patterns in terms of phaco time and corneal effects.

Purpose: To compare two different fragmentation patterns in femtosecond laser-assisted cataract surgery (FLACS) in terms of phaco values, postoperative endothelial cell count (ECC) and corneal thickness (CT).

Methods: This non-randomized, retrospective cross-sectional study included patients with senile cataract of grade 3 who underwent FLACS using the LenSx laser system. In Group 1 (32 eyes), lens fragmentation was created as a cross pattern.
