Purpose: To review the published literature on outcomes of keratolimbal allograft (KLAL) for the surgical treatment of limbal stem cell deficiency (LSCD) and corneal blindness after severe corneal chemical injury.
Methods: Literature searches were conducted in the following electronic databases: MEDLINE, EMBASE, Science Citation Index, CINAHL, LILACS and the Cochrane Library. Standard systematic review methodology was applied. The main outcome measure was the proportion of eyes with best-corrected visual acuity (BCVA) ≥20/200 at last follow-up. Other measures of allograft success were also collected.
Results: We identified six reports in which KLAL outcomes in the eyes after chemical injury could be distinguished. There were no randomised controlled studies. The outcomes of KLAL in 36 eyes of 33 patients were analysed. One study with seven eyes did not specify KLAL follow-up specific to chemical injury. Median postoperative follow-up for the other 29 eyes in 26 patients was 42 months (range 6.2-114 months). In the same 29 eyes, 69% (20/29) had BCVA ≥20/200 at the last follow-up examination. Eighty-nine per cent of all eyes (32/36) underwent penetrating keratoplasty simultaneous or subsequent to KLAL.
Conclusions: The number of studies where outcomes of KLAL in eyes with severe corneal chemical injury could be discerned was limited, and variability was observed in outcome reporting. The quality of evidence to support the use of KLAL in LSCD in severe chemical corneal burns was low. Standardisation and longer follow-up are needed to better define evidence-based best practice when contemplating surgical intervention for blindness after corneal chemical injury.

Department of Ophthalmology, Ege University Medical Faculty Hospital, Ege University, 35100, Bornova, Izmir, Turkey.
Purpose: To evaluate the severity distribution of chemical burn-induced Limbal stem cell deficiency (LSCD) according to the novel global consensus classification and to compare the treatment approach, before and after the global consensus.
Methods: Medical records of 127 eyes of 109 patients with LSCD were included. LSCD stages were categorized according to the global consensus classification published by "International LSCD Working Group".

Department of Ophthalmology, Kyorin University School of Medicine, 6-20-2 Shinkawa, Mitaka, Tokyo, 181-8611, Japan.
Purpose: Chemical chelation with ethylenediaminetetraacetic acid (EDTA) is an established treatment for calcific band keratopathy (CBK), whereas removal of calcium deposits from the subepithelial layer of the cornea may cause corneal irregularity. Using Fourier harmonic analysis, we analyzed the corneal topography in eyes with CBK treated by EDTA chelation.

Purpose: This study highlights the feasibility of femtosecond laser-assisted large-diameter lamellar corneal-limbal keratoplasty and its efficacy in the treatment of ocular surface failure caused by bilateral ocular chemical injury.
Observations: The series included 3 patients with ocular surface failure caused by bilateral ocular chemical burns. After dissection of the host cornea, a femtosecond laser-assisted large-diameter lamellar corneoscleral button, with varying thickness of 250-400 μm, was sutured to the recipient bed.

Current pharmacotherapy for DED is limited by a vicious inflammatory cycle in which reactive oxygen species (ROS) play a critical role. Additionally, topical eye drop therapy for DED often suffers from poor ocular availability due to multiple ocular surface barriers. Considering the key role of the ROS-NLRP3-IL-1β signaling axis in DED, in this investigation, fluorinated multifunctional polymer vesicles were developed for enhanced ocular surface penetration and synergistic DED therapy by combining ROS scavenging and immunomodulation.
