Peripheral corneal relaxing incisions based on anterior keratometry from Scheimpflug tomography versus Placido topography during standard cataract surgery.

Aim: To compare the outcomes of peripheral corneal relaxing incisions (PCRIs) based on standardized nomogram using keratometry from Scheimpflug and Placido machines during standard cataract surgery and to assess the astigmatism neutralization potential of PCRIs.

Methods: In this prospective, comparative case series of eyes with keratometric astigmatism between 0.75D to 2.

Posteriorly enclavated iris claw intraocular lens for aphakia: long-term corneal endothelial safety study.

Purpose: To report 2 years follow-up experience, corneal endothelial cell loss results, and A constant used in retroiridis-fixated iris-claw aphakic intraocular lens (IOL) secondary implantation to correct aphakia in eyes without adequate capsule support.

Methods: In this prospective, interventional, clinical case series, 16 consecutive eyes of 14 patients (13 adults and 1 child) underwent retroiridis implantation of Artisan iris-claw aphakic IOL (Ophtec BV, Groningen, the Netherlands). Outcome measures included spherical equivalent (SE) of refractive error, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA) expressed as the logarithm of the minimum angle of resolution (logMAR), endothelial cell density (ECD), and complications, including raised intraocular pressure (IOP) and pigment dispersion.

Intraocular pressure control with Ahmed glaucoma drainage device in patients with cicatricial ocular surface disease-associated or aniridia-related glaucoma.

To analyze the control of intraocular pressure (IOP) with an Ahmed glaucoma drainage device (AGDD) in two groups of glaucoma patients--one with cicatricial ocular surface disease (COSD) and one with aniridia. This is a retrospective comparative case series of nine patients (11 eyes) with COSD and six patients (8 eyes) with aniridia who underwent AGDD surgery to control IOP. The main outcome measure in both groups was stability of IOP between 6 and 21 mmHg.

Femtosecond laser-assisted lamellar keratoplasty (FSLK) for anterior corneal stromal diseases.

Our objective was to study the outcome of femtosecond-assisted lamellar keratoplasty (FSLK) in stromal corneal diseases. This is a retrospective chart review of 17 patients (20 eyes) who underwent FSLK for anterior corneal pathologies. Main outcome measures were refractive results following FSLK, complications, and graft survival.

Intraocular pressure control and corneal graft survival after implantation of Ahmed valve device in high-risk penetrating keratoplasty.

Purpose: To analyze the control of intraocular pressure (IOP) and corneal graft survival after implantation of Ahmed glaucoma device (AGD) in eyes that had high-risk penetrating keratoplasty (PK).

Methods: This is a retrospective noncomparative case series of 59 eyes that had high-risk PK and underwent AGD insertion. The primary outcome measures are the control of IOP between 6 and 21 mm Hg and corneal graft survival.

Outcomes of pseudophakic toric intraocular lens implantation in Keratoconic eyes with cataract.

Purpose: To evaluate the outcomes of pseudophakic toric intraocular lens (IOL) implantation in eyes with stable keratoconus and cataract.

Methods: Retrospective, noncomparative, case series of 12 eyes from 9 patients (mean age: 63.4±3.

Comparison of equivalent keratometric indices on Scheimpflug tomography with Placido-based topography system at different optical zones.

Aim: To compare Holladay equivalent keratometric indices on Scheimpflug tomographer and keratometry on Placido topographer at different optical zones.

Methods: In this observational study, 50 right eyes of 50 patients were recruited. All patients were scanned on both machines.

Endothelial keratoplasty: case selection in the learning curve.

Purpose: Many corneal surgeons are making the transition from penetrating keratoplasty to endothelial keratoplasty techniques such as Descemet's stripping endothelial keratoplasty and Descemet's stripping automated endothelial keratoplasty in the routine treatment of corneal endothelial failure. Donor dislocation is the commonest complication of these newer techniques. We set out to determine whether preoperative lens/iris diaphragm integrity might influence the rate of donor dislocation and whether donor endothelial failure was more common after surgical intervention for donor dislocation.

Management of angle-supported intraocular lens and iridectomy in Descemet-stripping endothelial keratoplasty.

Problem: Effective tamponade of a Descemet-stripping endothelial keratoplasty graft with a gas bubble requires that there is no route for the bubble to escape into the posterior chamber.

Solution: Exchange the angle-supported anterior-chamber intraocular lens (IOL) for an iris-enclaved Artisan IOL and position the IOL haptics over the peripheral iridectomy to occlude it to the extent that no gas can pass.
