Preserving posterior capsular integrity in post-endothelial keratoplasty posterior capsular opacification.

Endothelial keratoplasty (EK) with pseudophakia often presents with late-onset proliferative after-cataract with posterior capsule distension. We performed a modified technique of capsular bag lavage in 11 eyes with late-onset PCO after EK (4 cases: post-DSAEK, 7 cases: post-DMEK). Anterior capsular rim was separated from the underlying IOL optic using MVR blade.

Evaluation of various preservation media for storage of donor corneas.

Purpose: To compare the physical and microbiological characteristics of McCarey-Kaufman (MK), Cornisol, and Optisol-GS media and evaluate the outcomes of keratoplasty performed using corneas stored in these three media.

Methods: The study involved 60 donor corneas which were distributed in 3 groups: MK, Cornisol, and Optisol-GS. Corneas in these groups were further analyzed based on the type of keratoplasty performed (full thickness versus endothelial keratoplasty).

Femtosecond laser-assisted refractive capsulorhexis - Precise capsulotomy with accurate toric intraocular lens alignment.

Femtosecond laser-assisted cataract surgery with refractive capsulorhexis and toric intraocular lens (IOL) implantation was performed in 14 eyes with senile cataract and a preexisting regular corneal astigmatism of 1.5 D or more. Intraoperatively, the accuracy of the capsular rim marks was confirmed using the digital overlay of CALLISTO Eye and Z Align (Carl Zeiss Meditec, Germany).

Elucidating intraoperative dynamics and safety in posterior polar cataract with intraoperative OCT-guided phacoemulsification.

Purpose: To evaluate morphological characteristics and intraoperative dynamics of posterior polar cataract (PPC) using intraoperative optical coherence tomography (iOCT).

Setting: Rajendra Prasad Center for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India.

Design: Prospective interventional study.

Double crescentic edge separation for the management of cap-lenticular adhesion in small incision lenticule extraction.

We describe a modified technique of lenticule extraction for the management of cap-lenticular adhesions (CLAs). In cases where the lenticule edge could not be delineated, a Sinskey hook was introduced through the cap side-cut with the hook facing up (toward the cap), advanced to the periphery of lenticule at 3'o clock (for right-handed surgeons) and used to nudge the underside of the cap in the region of lenticule side-cut. The diagnosis of CLA was confirmed on observing a crescentic gap between the lenticule-side cut and the rolled lenticule edge.

Real-time intraoperative dynamics of white cataract-intraoperative optical coherence tomography-guided classification and management.

Purpose: To evaluate morphological characteristics and intraoperative dynamics of different types of white cataract using intraoperative optical coherence tomography (iOCT).

Setting: Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India.

Repeat keratoplasty in failed Descemet stripping automated endothelial keratoplasty.

Purpose: To evaluate the clinical factors associated with repeat Descemet stripping automated endothelial keratoplasty (DSAEK) or penetrating keratoplasty (PKP) in cases of failed DSAEK.

Methods: Retrospective observational study of cases with failed DSAEK admitted to our center for a repeat keratoplasty over 5 years (January 2013-Decemeber 2017) was undertaken. Demographic and perioperative details of all cases and type of repeat keratoplasty were recorded.

'Acute-angled bevel' sign to assess donor lenticule orientation in ultra-thin descemet stripping automated endothelial keratoplasty.

A 6.5-year-old boy with congenital hereditary endothelial dystrophy underwent clear corneal ultra-thin descemet stripping automated endothelial keratoplasty (DSAEK). After graft insertion, it was difficult to assess graft orientation due to hazy cornea.

Small incision lenticule extraction (SMILE) techniques: patient selection and perspectives.

Refractive lenticule extraction is becoming the procedure of choice for the management of myopia and myopic astigmatism owing to its precision, biomechanical stability, and better ocular surface. It has similar safety, efficacy, and predictability as femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and is associated with better patient satisfaction. The conventional technique of small incision lenticule extraction (SMILE) involves docking, femtosecond laser application, lenticule dissection from the surrounding stroma, and extraction.

Optimizing outcomes with toric intraocular lenses.

Toric intraocular lenses (IOLs) are the procedure of choice to correct corneal astigmatism of 1 D or more in cases undergoing cataract surgery. Comprehensive literature search was performed in MEDLINE using "toric intraocular lenses," "astigmatism," and "cataract surgery" as keywords. The outcomes after toric IOL implantation are influenced by numerous factors, right from the preoperative case selection and investigations to accurate intraoperative alignment and postoperative care.

Combined Hamartoma of the Retina and Retinal Pigment Epithelium: An Optical Coherence Tomography-Based Reappraisal.

Purpose: To analyze the optical coherence tomography (OCT) characteristics of combined hamartoma of the retina and retinal pigment epithelium (CHRRPE) involving the macula.

Design: Retrospective, observational case series.

Methods: setting: Single institutional.
