Mokumu D, Hu W, Damaola A, Wu J. Interface fluid syndrome after small incision lenticule extraction surgery secondary to posner schlossman syndrome - A case report. Heliyon 2023; 9:e21863. [PMID: 38027722 PMCID: PMC10663904 DOI: 10.1016/j.heliyon.2023.e21863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 10/17/2023] [Accepted: 10/30/2023] [Indexed: 12/01/2023] Open
Abstract
Purpose This report describes a case of interface fluid syndrome (IFS) secondary to Posner Schlossman Syndrome (PSS) following small incision lenticule extraction (SMILE) surgery. Case presentation A 19-year-old male was diagnosed with IFS secondary to PSS in his left eye 1 month after undergoing SMILE. Detailed patient history and clinical findings, auxiliary examination results, and short-term follow-up are reported. In this patient, the IFS was caused by elevated intraocular pressure (IOP) due to PSS. Treatment with topical steroids in combination with anti-glaucoma drops led to complete regression of the fluid, and there was no recurrence during a 7-month follow-up period. Conclusion IFS is a potential complication of SMILE, and anterior segment ocular coherence tomography (AS-OCT) can definitively diagnose the condition. This case demonstrates that the treatment for IFS should be based on the underlying cause, and requires prompt and vigorous management for resolution.

Abstract
Background To present a case with a history of laser in situ keratomileusis (LASIK) developing diffuse lamellar keratitis (DLK) after diamond burr superficial keratectomy (DBSK) for recurrent corneal erosion (RCE). Case presentation A 25-year-old man presented with multiple episodes of RCE one year after femtosecond-assisted LASIK for myopia correction. Because conservative treatments failed to halt the repetitive attack of RCE, he underwent epithelial debridement and DBSK. However, severe foreign body sensation and blurred vision developed on postoperative day one. The next day, slit lamp biomicroscopy revealed DLK manifested as diffuse granular infiltrates at the flap interface. After topical corticosteroid treatment, the inflammation resolved gradually, and his vision recovered to 20/20. Conclusions Diffuse lamellar keratitis is a rare post-LASIK complication that can be triggered by DBSK, which causes impairment of the corneal epithelial integrity and subsequent inflammation at the flap interface. For post-LASIK patients with RCE, alternative treatments, such as anterior stromal puncture, may be considered to avoid extensive disruption of corneal epithelium and DLK development depending on the size and the location of the lesions.

Abstract
This research exhibits the design of a feasible, enzyme-free and sensitive fluorescent sensing assay for the detection of Staphylococcus aureus (S. aureus), using self-circulation of molecular beacons. With protein A on S. aureus as identifying target, the capture probe binds on the surface of S. aureus based on interaction between its aptamer section and protein A. Recognition of protein A by aptamer section in capture probe leads to allosterism of capture probe, exposing initiator section to activate the following self-circulation. After multiple circulation-based signal amplification, the method exhibits a favorable detection sensitivity and shows a promising prospect for the keratitis-related pathogenic bacteria detection. The highlights of the sensing assay are as follows: (i) capture probe is designed with aptamer section which endows the method a high selectivity; (ii) signal of bacteria is converted to nucleic acid signal after recognition of target bacteria by capture probe; and (iii) high sensitivity of method is derived from the self-circulation process. Therefore, we believe that the strategy can provide a useful platform for target bacteria detection and thus contribute to the diagnosis of infectious diseases.

Abstract
A man aged 26 years presented with complaints of diminution of vision in his right eye for 1 year following a fist injury. He had a history of laser-assisted in situ keratomileusis in both eyes 5 years earlier. On examination, his uncorrected distance visual acuity (UDVA) in the right eye was 1.0 logMAR. Slit-lamp examination of the right eye revealed a superotemporal dislocation of the flap with coexisting epithelial ingrowth encroaching the pupillary area. Due to the presence of long-standing fixed flap folds, a flap amputation was performed along with removal of the epithelial ingrowth using 0.02% mitomycin C as adjunct. Postoperatively, the UDVA was 0.3 logMAR on day 1, which improved to 0.2 logMAR at 1 week. At 1 year, the UDVA was 0.2 logMAR improving to 0.1 logMAR with refraction, with minimal paracentral corneal haze and no signs of corneal ectasia.

Five-Year Incidence, Management, and Visual Outcomes of Diffuse Lamellar Keratitis after Femtosecond-Assisted LASIK. J Clin Med 2021; 10:jcm10143067.

Abstract
Femtosecond (FS) lasers initially had a higher incidence of diffuse lamellar keratitis (DLK) compared with microkeratome flap creation. It has been theorized that higher-frequency lower-energy (HFLE) FS lasers would reduce the incidence of DLK. Our study sought to evaluate the incidence of newer HFLE FS lasers with pulse frequencies above 60 kHz. It was a retrospective case-control study evaluating the incidence of DLK following flap creation with one of three FS lasers (AMO iFs, WaveLight FS200, Zeiss VisuMax). Uncomplicated LASIK cases were included as the control group (14,348 eyes) and cases of DLK were recorded in the study group (637 eyes). Of the 637 cases of DLK, 76 developed stage II, 25 progressed to stage III, and only three developed stage IV DLK. The overall incidence rate of DLK was 4.3%; it has fallen with the invention of newer HFLE FS lasers and is approaching the DLK incidence rates of DLK with microkeratome.

Abstract
PURPOSE To report a case of diffuse lamellar keratitis (DLK) after corneal collagen cross-linking in an eye with a remote history of laser in situ keratomileusis (LASIK) surgery. METHODS This is a case report and literature review. RESULTS This report describes the development of unilateral stage IV DLK in a patient who underwent bilateral corneal cross-linking for corneal ectasia 18 years after LASIK surgery. The patient was treated with high-dose topical steroids that were tapered over 1 month and multiple flap lifts. The ultimate best-corrected visual outcome was 20/60. CONCLUSIONS DLK is a potential sight-threatening complication of refractive surgery that can occur at any time in the postoperative period, even years after the procedure. Undergoing a subsequent corneal procedure that may disrupt or promote inflammation within the surgical flap-stromal interface, such as corneal collagen cross-linking, is a recognized risk factor for the development of DLK. This case suggests that patients with any history of LASIK surgery undergoing corneal cross-linking or other lamellar corneal surgeries may benefit from closer follow-up (eg, daily) than patients with no history of LASIK.

Abstract
PURPOSE To report the French refractive surgeons' real-life practices for preventing infection after corneal refractive surgery (photorefractive keratotomy [PRK], laser in situ keratomileusis [LASIK], and small-incision lenticule extraction). SETTING France. DESIGN Anonymous practice survey. METHODS The questionnaire was sent in a single email invitation to 400 declared refractive surgeons. The following information was recorded between December 2019 and April 2020, before the coronavirus pandemic: demographics data, preoperative evaluation and preparation of the patient, surgical management, immediate and postoperative protocol, and infections reported after corneal refractive surgery. RESULTS Eighty-three of 400 surgeons (20.75%) responded to the questionnaire; 55 (66.0%) performed more than 50 corneal refractive surgeries a year, and 25 (30.1%) performed more than 200 procedures a year. Thirty-six (43.4%) surgeons wore 3 protective items, 37 (44.6%) 2, 5 (6.0%) 1, and 5 (6.0%) zero. Seventy-seven (92.8%) surgeons used povidone-iodine for skin area disinfection and 54 (65%) for conjunctival fornix disinfection. The contact time of povidone-iodine was less than 3 minutes for 71 (85.0%) surgeons. Twenty surgeons (24.1%) reported at least 1 postrefractive surgery infection. Twenty percent of surgeons who wore sterile gloves for PRK reported postoperative infections compared with 62.5% for those who did not (P = .008). These figures were, respectively, 8.7% and 66.7% for the use of sterile gloves during LASIK (P = .002); 8.9% of surgeons who wore surgical masks for LASIK reported postoperative infections compared with 50.0% for those who did not (P = .01). CONCLUSIONS Practices are variable among French refractive surgeons. Wearing a surgical mask and sterile gloves during corneal refractive surgery appears to be advisable.
