Purpose: To demonstrate the efficacy and safety of deep lamellar keratoplasty(DLKP) in the treatment of corneal opacity in severe ocular surface disease.
Methods: A total of 12 eyes of 11 patients were analyzed in this retrospective case series. The original diseases were Stevens Johnson syndrome (SJS : 3 eyes), ocular ciccatricial pemphigoid(OCP : 2 eyes), thermal burns (2 eyes), limbal deficiency due to unknown cause (2 eyes), and corneal scarring due to trachoma (3 eyes). Cases with total limbal deficiency (6 eyes) were also treated with secondary or simultaneous limbal transplantation. Cataract surgery was also performed in 4 eyes following DLKP.
Results: DLKP was successfully done in all cases. One case with SJS experienced an immunological rejection against the limbal graft. Two eyes with SJS eventually developed ulcers that required therapeutic penefrating keratoplasty. Visual improvement was observed in 9 out of 12 eyes, of which 2 cases maintained a corrected visual acuity of 0.1 despite conjunctivalization of the ocular surface.
Conclusion: DLKP is an effective means to treat stromal opacity in patients with ocular surface disease.

Ocular surface chemical injuries often result in permanent visual impairment and necessitate complex, long-term treatments. Immediate and extensive irrigation serves as the first-line intervention, followed by various therapeutic protocols applied throughout different stages of the condition. To optimize outcomes, conventional regimens increasingly incorporate biological agents and surgical techniques.

Introduction: This study compared the clinical outcomes of allogenic cultured limbal epithelial transplantation (ACLET) and cultivated oral mucosal epithelial transplantation (COMET) in the management of limbal stem cell deficiency (LSCD).
Methods: Forty-one COMET procedures in 40 eyes and 69 ACLET procedures in 54 eyes were performed in the Corneoplastic Unit of Queen Victoria Hospital, East Grinstead. Data were examined for demographics, indications, ocular surface stability, absence of epithelial defect, ocular surface inflammation, visual outcomes, and intra- and postoperative complications.
Atrophic meibomian gland dysfunction induced by eyelid margin cryotherapy with liquid nitrogen.

Eye Hospital, The First Affiliated Hospital of Harbin Medical University, Harbin, China.
To develop an atrophic Meibomian Gland Dysfunction (MGD) animal model via liquid nitrogen cryotherapy, the eyelid edges of C57 mice exposure to liquid nitrogen for 30 s. Morphology of MG and ocular surface were assessed using stereomicroscopy and a slit lamp microscope at multiple time points post-injury. Acinar loss and atrophy were observed from day 7, with increased inflammation and apoptosis, and decreased proliferation in acinar cells.

Introduction: Meibomian Gland Dysfunction (MGD) represents the most common cause of dry eye disease (DED). Traditional treatments mainly rely on heating and liquifying the meibum to favor its expression. However, recent knowledge advances have led to the development of novel therapies specifically designed for patients with MGD.
