ABSTRACT
Custard apple seeds have been used in native medicine from time immemorial for the management of head lice and skin exfoliation. We report six consecutive patients who developed toxic keratoconjunctivitis within 6–12 h of ocular exposure to custard apple seeds. The use of topical steroid worsens the toxicity and predisposes to the development of microbial keratitis in such cases. Patients showed a good response to primary treatment with topical fortified antibiotics and lubricants. This case series highlights the need to educate the patients regarding the potential toxic effects of the custard seeds and the treating physicians about possible deleterious effects on using topical steroid.
ABSTRACT
We report the case of a 76-year-old woman who presented to us with bilateral simultaneous Descemet’s membrane detachment (DMD) after successful uneventful cataract surgery of both eyes in the late post-operative period. The first eye was operated 1-week prior to the second eye. We shall also discuss different hypothesis of an underlying predisposition to DMD and in our case the possible role of a thick arcus senilis in the etiology of DMD. Surgical intervention with 14% octafluoropropane (C3F8) gas injection in the anterior chamber resulted in excellent visual acuity restoration in the patient.
ABSTRACT
Aim: To study the safety and efficacy of sutureless femtosecond anterior lamellar keratoplasty (FALK) in patients with corneal stromal opacities. Materials and Methods: Eleven eyes of 11 consecutive patients with corneal stromal opacities involving <250 μ due to various pathologies were included in the study. Preoperatively, all underwent anterior segment imaging with spectral domain optical coherence tomography (SD‑OCT) (Bioptigen Inc., Durham, North Carolina, USA) to measure the depth of the stromal opacity. All patients underwent FALK, and bandage contact lens was placed for a period of 2 weeks. Postoperatively, uncorrected visual acuity, best corrected visual acuity (BCVA), and SD‑OCT evaluation were performed. Results: All patients showed significant improvement in BCVA. The mean postoperative BCVA (in decimals) improved from 0.11 ± 0.06 preoperatively to 0.59 ± 0.08. There were no intraoperative or significant postoperative complications that were noticed. Conclusion: FALK is a safe and effective alternative to deep anterior lamellar keratoplasty or penetrating keratoplasty in the treatment of anterior stromal opacities.
ABSTRACT
Purpose: To assess the efficacy and advantages of femtosecond laser enabled keratoplasty (FLEK) over conventional penetrating keratoplasty (PKP) in advanced keratoconus. Materials and Methods: Detailed review of literature of published randomized controlled trials of operative techniques in PKP and FLEK. Results: Fifteen studies were identified, analyzed, and compared with our outcome. FLEK was found to have better outcome in view of better and earlier stabilization uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and better refractive outcomes with low astigmatism as compared with conventional PKP. Wound healing also was noticed to be earlier, enabling early suture removal in FLEK. Conclusions: Studies relating to FLEK have shown better results than conventional PKP, however further studies are needed to assess the safety and intraoperative complications of the procedure.
