    1. Intralenticular changes in eyes with mature senile cataract on modified posterior segment optical coherence tomography

      Intralenticular changes in eyes with mature senile cataract on modified posterior segment optical coherence tomography

      Purpose: To study the morphological changes within mature senile cataracts on modified posterior segment optical coherence tomography (OCT). Methods: A cross-sectional observational study recruiting patients of mature cataracts admitted for elective cataract surgery in tertiary eye care. A modified OCT imaging of the lens was done and lenticular findings were noted by a single observer. Corresponding slit-lamp biomicroscopic findings and intraoperative experiences were also noted by a second observer and respective surgeons. Results: Forty-four eyes of 44 patients were included. The mean age of patients was 65 ± 5.7 years. The intralenticular findings were uniform in groups of eyes, and ...

    2. Intraoperative assessment of corneal injuries using microscope-integrated optical coherence tomography

      Intraoperative assessment of corneal injuries using microscope-integrated optical coherence tomography

      A 2-year-old male child presented to the ocular emergency following penetrating injury with a metallic foreign body. Clinical examination revealed a nasal corneal perforation with iris tissue prolapse [ [Figure 1] , yellow arrow ]. To further delineate the extent of the corneal perforation and associated anterior segment changes, integrated optical coherence tomography (iOCT) was used. It showed corneal wound gaping for entire corneal thickness from the paracentral region to the periphery of the cornea. Within the gaping, prolapsing hyperreflective tissue was made out in continuity with the iris tissue onto the surface of the epithelium, suggestive of iris tissue [Figure 2] a ...

    3. Surgical removal of a giant iris stromal cyst: an intraoperative optical coherence tomography-guided approach

      Surgical removal of a giant iris stromal cyst: an intraoperative optical coherence tomography-guided approach

      An 11-year-old girl was brought with the chief complaint of progressive diminution of vision in her right eye for the past 3 months. There was no history of ocular trauma or any ocular surgery. Systemic and family history was insignificant. Visual acuity was 20/20 in her left eye and counting finger close to face with projection of rays being accurate in her right eye. Slit lamp examination of her right eye showed large cystic lesion filling almost entire anterior chamber. With the help of various imaging modalities like anterior segment optical coherence tomography (OCT) and ultrasound biomicroscopy diagnosis of ...

    4. Intraoperative Optical Coherence Tomography–Guided Management of Cap–Lenticule Adhesion During SMILE

      Intraoperative Optical Coherence Tomography–Guided Management of Cap–Lenticule Adhesion During SMILE

      PURPOSE: To report successful lenticule extraction using intraoperative optical coherence tomography (OCT) in a case of cap–lenticule adhesion during small incision lenticule extraction (SMILE). METHODS: Case report. RESULTS: A 22-year-old patient with a refractive error of −5.00 −0.50 × 120° and −5.00 −0.75 × 60° in the right and left eyes, respectively, was scheduled for SMILE. The lenticule was created using the VisuMax femtosecond laser system (Carl Zeiss Meditec, Jena, Germany). The surgeon experienced difficulty while extracting the lenticule in the right eye. The patient was immediately shifted under the surgical microscope integrated with intraoperative OCT. The ...

    5. Rescuing the host Descemets membrane in full-thickness traumatic wound dehiscence in deep anterior lamellar keratoplasty: intraoperative optical coherence tomography (iOCT)-guided technique

      Rescuing the host Descemets membrane in full-thickness traumatic wound dehiscence in deep anterior lamellar keratoplasty: intraoperative optical coherence tomography (iOCT)-guided technique

      Optimal visual recovery following full-thickness traumatic wound dehiscence in a case of operated deep anterior lamellar keratoplasty (DALK) is rarely seen. Here we report a case of 22-year-old male patient presented to our casualty department with complaint of sudden-onset diminution of vision in his right eye following blunt trauma of 1 day duration. DALK had been performed 11 months ago for advanced keratoconus in the same eye. Best-corrected visual acuity (BCVA) in the right eye was hand movement close to face with accurate projection of rays and in the left eye was 20/20. Slit-lamp examination showed the presence of ...

    6. Microscope-integrated intraoperative optical coherence tomography-guided small-incision lenticule extraction: New surgical technique

      Microscope-integrated intraoperative optical coherence tomography-guided small-incision lenticule extraction: New surgical technique

      We describe the surgical technique of microscope-integrated intraoperative optical coherence tomography (OCT)-guided small-incision lenticule extraction. The technique enables manual tracking of surgical instruments and identification of the desired dissection plane. It also helps discern the relation between the dissector and the intrastromal lenticule. The dissection plane becomes hyperreflective on dissection, ensuring complete separation of the intrastromal lenticule from the overlying and underlying stroma. Inadvertent posterior plane entry, cap–lenticule adhesion, incomplete separation of the lenticule, creation of a false plane, and lenticule remnants may be recognized intraoperatively so corrective steps can be taken immediately. In cases with a hazy ...
