    1. Microscope Integrated Intraoperative Optical Coherence Tomography-Guided DMEK in Corneas with Poor Visualization

      Microscope Integrated Intraoperative Optical Coherence Tomography-Guided DMEK in Corneas with Poor Visualization

      Purpose: To assess the utility of microscope-integrated intraoperative optical coherence tomography (Mi-OCT) for performing Descemet membrane endothelial keratoplasty (DMEK) in corneas with poor visualization. Methods: It is a prospective interventional case series that included 25 consecutive cases of corneal decompensation with poor visualization that underwent Mi-OCT-guided DMEK at a tertiary eye care centre. The main outcome measures were graft attachment on day 3 and requirement for re-bubbling. Results: The etiology for corneal decompensation was pseudophakic bullous keratopathy (n=17), Fuchs endothelial corneal dystrophy (n=4), failed graft (n=2), iridocorneal endothelial syndrome (n=1) and failed Descemet stripping automated endothelial ...

    2. Intraoperative optical coherence tomography-guided release of lenticulo-corneal adhesion and lens aspiration in anterior dislocation of lens with corneal edema

      Intraoperative optical coherence tomography-guided release of lenticulo-corneal adhesion and lens aspiration in anterior dislocation of lens with corneal edema

      Purpose: To describe the outcome of microscope integrated optical coherence tomography (MiOCT) guided removal of lenticulo-corneal adhesion and intralenticular lens aspiration (ILLA) in cases with anterior dislocation of the crystalline lens and corneal edema. Methods: MiOCT-guided ILLA was performed in three eyes of two cases of homocystinuria with spontaneous anterior dislocation of lens and corneal edema. Lenticulo-corneal adhesion was noted intraoperatively, which was not apparent pre-operatively. The lenticulo-corneal adhesion could be successfully peeled using intravitreal forceps and viscodissection with visco-dispersive viscoelastic under the guidance of MiOCT. Results: In all cases, the lenticulo-corneal adhesion could be successfully removed without any complication ...

    3. Intrastromal fluid drainage with air tamponade: anterior segment optical coherence tomography guided technique for the management of acute corneal hydrops

      Intrastromal fluid drainage with air tamponade: anterior segment optical coherence tomography guided technique for the management of acute corneal hydrops

      Aims To describe a new technique of corneal stab incision with intracameral air injection for management of patients with acute corneal hydrops. Methods Five patients with acute corneal hydrops with large Descemet's membrane (DM) detachment and multiple stromal clefts underwent the procedure. The technique entailed anterior segment optical coherence tomography guided intrastromal fluid drainage through multiple corneal stromal venting incisions along with anterior chamber air tamponade. The time taken for the DM to reattach, resolution of corneal oedema and the best-corrected visual acuity (BCVA) were assessed postoperatively. Results Five patients (age range, 10–25 years) with large DM detachment ...

    4. Spectral domain optical coherence tomography

      Spectral domain optical coherence tomography
      Over the last 20 years, imaging of the eye has significantly grown in importance for the diagnosis of ocular diseases. Out of a variety of techniques such as scanning laser polarimetry (SLP) and confocal scanning laser ophthalmoscopy (SLO), optical coherence tomography (OCT) has emerged at the forefront of ocular imaging because of the wide variety of information it can provide, its high resolution, and the complex data it is able to gather. The Spectral Domain OCT (SDOCT) introduced recently has come as an advantage over the previous technology of Time Domain OCT (TDOCT) in being able to handle and analyze ...
