AI Article Synopsis
- The study focused on the outcomes of ipsilateral rotational keratoplasty (IRK) combined with cataract extraction in 17 patients with trachoma in Oman over three years.
- Out of 25 operated patients, 17 were followed for one year, with results indicating significant visual improvement, particularly in patients with both trachoma and trauma.
- The findings suggest that IRK with cataract extraction can effectively restore ambulatory vision in patients facing challenges in accessing donor grafts and postoperative care in developing countries.
Article Abstract
Aim: To report on the results of visual rehabilitation by ipsilateral rotational keratoplasty (IRK) and cataract extraction in 17 patients with trachoma and with trachoma and trauma in Oman over 3 years.
Patients: Of 25 patients operated from 2001-2004 with IRK, extracapsular cataract extraction, and intraocular lens implantation, 17 eyes of 17 patients with cicatricial trachoma (WHO stage CO) could be followed up after 1 year. Group 1 comprised 11 eyes with ciatricial trachoma. In group 2, six eyes had additional traumatic corneal scars.
Methods: Surgery was performed using a motor trephine Keratron (Geuder), the Accurus 800 (Alcon) phacovitrectomy machine, and calculation for intraocular lens implantation (IOL: MZ60BD, Alcon) with a topography (Atlas, Humphrey Zeiss)-supported SRK II formula (OcuScanRxP, Alcon).
Results: Although only four of 17 patients had preoperative visual acuity (VA) at 5 m and one of 17 had VA at 1 m, postoperatively seven of 17 patients gained VA at 5 m and six of 17 at 1 m. Ambulatory vision was regained in 13 of 17 (78%) patients. Patients with trachoma and trauma benefited more from the surgery [vision increase in trachoma: eight of 11 eyes (73%); trachoma and trauma: five of five eyes (100%)]. Postoperative spherical refraction was -12.0D to +4.0D (median:+4.0D), and astigmatism ranged from 10D to 0.3D (median 5.35D). One eye was lost because of uncontrolled keratitis.
Conclusions: IRK with cataract extraction may provide ambulatory vision in patients with cicatricial trachoma and secondary dry eye syndrome living in developing countries where donor grafts are difficult to obtain and where postoperative follow-up of high-risk keratoplasty is impaired.

Background Recommendations regarding long-term postoperative activity are intended to prevent adverse events, but no common policy or best practice exists among ophthalmologists for pediatric patients. We surveyed ophthalmologists on their postoperative guidelines after the one-month postoperative period following childhood cataract and glaucoma surgeries. Methods A 28-question anonymous Qualtrics survey was distributed via listservs and social media.

Background: Endothelin is a potent vasoconstrictor and contributes to the regulation of vascular perfusion. Aberrant endothelin-1 (ET-1) levels in aqueous humor have been reported across a variety of vascular diseases of the eye, including glaucoma. These findings suggest that dysregulation of ET-1 production may contribute to glaucoma pathophysiology.

Purpose: We aimed to evaluate the effects of autologous serum plus artificial tears on corneal sensation and tear film stability in patients with mild to moderate xerophthalmia after cataract surgery.
Methods: A total of 150 patients with mild to moderate xerophthalmia after one-time cataract surgery from March 2022 to September 2023 were selected and randomly divided into a control group (n = 75) and a study group (n = 75). The control group was treated with artificial tears (polyvinyl alcohol eye drops), while the study group was given autologous serum plus artificial tears.

Purpose: To describe a three-phase surgical approach for managing progressive visual decline in a patient with myopia magna and a history of epikeratophakia.
Methods: A 55-year-old woman with previous epikeratophakia surgery in both eyes experienced progressive visual deterioration. The three-phase approach included: (1) removal of the epikeratophakia lenticule, (2) cataract extraction with intraocular lens implantation, and (3) transepithelial topography-guided photorefractive keratectomy (trans-PRK).
