"En bloc" combined 270-degree keratolimbal allograft with central lamellar keratoplasty for severe limbal stem cell deficiency secondary to mustard gas exposure.

Background: Severe limbal stem cell deficiency (LSCD) resulting from chronic and delayed-onset mustard gas keratopathy (MGK) presents substantial management challenges. This article introduces an "en bloc" surgical procedure combining a 270-degree keratolimbal allograft (KLAL) with central lamellar keratoplasty (CLK) as a novel approach to treat this condition.

Methods: A retrospective case series was conducted at Labbafinejad Medical Center in Tehran, Iran, from 2002 to 2019, including 13 eyes from 13 male patients diagnosed with chronic and delayed-onset MGK.

Lately Diagnosed Acanthamoeba Keratitis Manifesting as an Intrastromal Corneal Abscess: A Case Report.

A 42-year-old female contact lens wearer presented to a local emergency department with a 3-day history of decreased vision and ocular discomfort in her right eye. She was started on topical fluorometholone and oral acyclovir with initial diagnosis of herpes simplex keratitis. After 3 weeks of worsening symptoms, she was diagnosed with bacterial corneal ulcer and treated with levofloxacin eye drops every 2 hr.

Effective Combination Therapy with Human Amniotic Membrane Mesenchymal Stem Cells and Low-Level Laser Therapy in Wound Healing in Animal Models.

Many studies have recognized the importance of new methods in wound healing. This study aims to investigate the healing effects of allograft extra embryonic mesenchymal stem cells (MSCs) with and without low-level diode laser irradiation when grafted into full-thickness skin defects in diabetic animal models. In this experimental study, in order to make the rats diabetic, we used an intra-peritoneal injection of streptozotocin.

Pars plana lensectomy and iris-claw Artisan intraocular lens implantation in patients with Marfan syndrome.

Rational: The rationale of this study was to evaluate the visual and anatomical outcomes of pars plana lensectomy and iris-claw Artisan intraocular lens (IOL) implantation in patients with subluxated crystalline lenses secondary to Marfan syndrome.

Materials And Methods: In this retrospective case series, we evaluate the records of 21 eyes of 15 patients with Marfan syndrome and moderate-to-severe crystalline lens subluxation who underwent pars plana lensectomy/anterior vitrectomy and implantation of iris-claw Artisan IOL at referral hospital from September 2015 to October 2019.

Results: Twenty-one eyes of 15 patients (10 males and five females) with a mean age of 24.

Outcomes of combined phacoemulsification/intraocular lens implantation and silicon oil removal.

Purpose: To evaluate the outcomes and complications of simultaneous silicon oil removal (SOR) and phacoemulsification and intra ocular lens implantation.

Methods: In this retrospective non-comparative case series, the visual, refractive and anatomical outcomes of patients who underwent combined phacoemulsification/silicone oil removal (5700 centistokes) surgery between 2017 and 2019 in a single center were evaluated.

Results: Forty-four eyes of 44 patients (eighteen males) were included.

Secondary Piggyback Intraocular Lens for Management of Residual Ametropia after Cataract Surgery.

Purpose: To investigate the indications, clinical outcomes, and complications of secondary piggyback intraocular lens (IOL) implantation for correcting residual refractive error after cataract surgery.

Methods: In this prospective interventional case series, patients who had residual refractive error after cataract surgery and were candidates for secondary piggyback IOL implantation between June 2015 and September 2018 were included. All eyes underwent secondary IOL implantation with the piggyback technique in the ciliary sulcus.

Characterization of In Vivo Biomechanical Properties in Macular Corneal Dystrophy.

Purpose: To measure and compare corneal biomechanics in patients with macular corneal dystrophy (MCD), versus those who underwent penetrating keratoplasty (PK) for MCD, versus normal subjects.

Design: Cross-sectional study.

Methods: This study enrolled 24 eyes with MCD, 25 eyes that underwent PK in patients with preoperative diagnosis of MCD, and 28 normal eyes.

Peripheral Hypertrophic Subepithelial Opacities of Corneal Grafts After Deep Anterior Lamellar Keratoplasty.

Purpose: To investigate possible underlying etiologies of the development of peripheral graft hypertrophic subepithelial opacities (PGHSO) and to evaluate the effects of these opacities on visual outcomes after deep anterior lamellar keratoplasty (DALK).

Methods: This prospective, interventional case series enrolled 29 eyes with keratoconus that underwent DALK and developed PGHSO (group 1). The control group consisted of 32 eyes with keratoconus that underwent DALK during the same period and had a clear graft at the final examination (group 2).
