“…under intracameral anesthesia at a top-level surgical facility (Quirófanos El Tesoro) in Medellín, Colombia, using a standardized and already published protocol. 4 For both eyes, the surgical protocol was similar: the periocular area was cleaned and the patient was draped; then, a 1.2 mm paracentesis and a 2.8 mm main incision were created, and the anterior chamber was filled preservative-free lidocaine. After allowing 30 seconds for the anesthetic to take effect, it was replaced with a sodium hyaluronate 2.4% ophthalmic viscosurgical device (OVD).…”

Introduction:The requirement to perform immediate sequential bilateral cataract surgery (ISBCS) is controversial. Most surgeons who do not adhere to this approach cite the possibility of bilateral complications occurring.Patient and Clinical Findings: A 35-year-old woman underwent bilateral implantation of phakic intraocular lenses the same day. She complained of pain and significantly decreased quality of vision in her right eye 12 hours postoperatively and was immediately examined. Physical examination of the right eye showed significant corneal edema extending from limbus to limbus and a dilated fixed pupil unresponsive to light.Diagnosis, Intervention, and Outcomes: Physical examination showed toxic anterior segment syndrome ensued in one eye. The complication was timely managed, preventing further damage to the eye. The contralateral eye showed no signs of complication.Conclusions: This case highlights that, when performed with utmost care, protocols designed to avoid bilateral occurrence of complications in same-day surgeries can work in the real-world settings. This is further evidence that ISBCS may not pose an additional risk to patients.

“…1 Treatment of KC includes rigid gas-permeable contact lenses, ICRS implantation, corneal surface ablation combined with corneal crosslinking (CXL), phakic toric intraocular lens implantation, and lamellar or penetrating keratoplasty. [2][3][4][5] Corneal Allogenic Intrastromal Ring Segments (CAIRS), of a donor cornea were also used in patients with keratoconus. 6 The ICRS was first introduced by Blevatskaya in 1966 to treat myopia and later used by Colin 3 in 2000 to treat KC.…”

To study the compensatory corneal epithelial changes after femtolaser-assisted intracorneal ring segment (ICRS) implantation in early and moderate cases of keratoconus (KC) using anterior segment optical coherence tomography (AS-OCT). Patients and Methods: A prospective observational non-randomized study of 40 eyes with mild to moderate KC received femtolaser-assisted ICRS implantation. Ferrara ICRS with different arc lengths and thicknesses were used according to the patients' tomographic pattern. Patients had a clear central cornea, keratometry reading < 60 diopters, and corneal thickness > 400 microns. AS-OCT was performed preoperatively and at 1, 3, and 6 months after surgery. Corneal epithelial thickness (CET) was measured over 17 points (2 mm central and 16 points on 2-5 mm and 5-7 mm annular zones) over the pupil center. All data were collected and analyzed. Results: Comparing the preoperative and postoperative data, there was a statistically significant increase in the CET postoperatively throughout the 6-month follow-up period in all zones (p<0.001). The epithelial thickness (ET) was noticed shortly around and central to the ring ridges by the first month (5-7 mm zone). By the third month, the flattened central cornea (2 mm zone) and the 2-5 mm zone showed a significant increase in ET up to the 6th month. Conclusion: ICRS implantation in KC results in a thicker and more regular epithelium in the central corneal zone as a secondary response to the corneal stromal changes induced by the implants.

“…El implante de lentes intraoculares fáquicos (LIO-F) es una técnica extremadamente efectiva y segura para corregir ametropías severas, en pacientes sanos y con anormalidades corneales 1 . El riesgo de desarrollar cataratas luego de esta cirugía es extremadamente bajo 2 y puede relacionarse con la aparición de un vault anormalmente bajo, lo cual es en sí mismo una compilación también muy rara 3 .…”
