Delayed-onset pressure-induced interlamellar stromal keratitis (PISK) and interface epithelial ingrowth 10 years after laser-assisted in situ keratomileusis. Am J Ophthalmol Case Rep 2023; 32:101874.

Abstract
Purpose To report a case of pressure-induced interlamellar stromal keratitis (PISK) 10 years after laser assisted in situ keratomileusis (LASIK). Observations A case of a 36-year-old man who underwent LASIK and presented with PISK 10 years later. Before presenting to our department he consulted elsewhere for red eye, decreased visual acuity, foreign body sensation, and pain on the RE for 1 week. He was then prescribed topical prednisolone six times per day and was lost to follow-up. On examination and after 1 month of continuous use of steroids uncorrected distance visual acuity (UCDV) was 20/400 in the right eye (RE) and 20/20 in the left eye (LE). Best corrected visual acuity was 20/80 on the RE. The Goldmann intraocular pressure (IOP) was 26 and 17 mmHg in the RE and LE, respectively. Slit lamp biomicroscopy revealed fluid in the interface and epithelial ingrowth. Fundoscopic examination results were normal in both eyes. Treatment was initiated with topical brimonidine tartrate 0.2%, timolol 0.5%, and dorzolamide 2.0% BID. Once the pressure was controlled the patient was scheduled for mechanical debridement of the epithelial ingrowth with significant improvement of UCVA (20/25). Conclusions Refractive surgeons should be aware of PISK as a potential complication of LASIK even years after the procedure. Intraocular pressure can be misleading, and diligent and careful examination are key to diagnosis and treatment of this potentially blinding complication.

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
Epidemiological and genetic studies provide strong evidence supporting an association between myopia and glaucoma. The accurate detection of glaucoma in myopic eyes, especially those with high myopia, remains clinically challenging due to characteristic morphologic features of the myopic optic nerve in addition to limitations of current optic nerve imaging modalities. Distinguishing glaucoma from myopia is further complicated by overlapping perimetric findings. Therefore, longitudinal follow-up is essential to differentiate progressive structural and functional abnormalities indicative of glaucoma from defects that may result from myopia alone. Highly myopic eyes are at increased risk of complications from traditional incisional glaucoma surgery and may benefit from newer microinvasive glaucoma surgeries in select cases.

Abstract
Interface fluid syndrome (IFS) is a complication associated with laser in situ keratomileusis (LASIK) surgery where a fluid pocket in the corneal stroma decreases visual acuity. A systematic review of IFS cases using PRISMA guidelines was performed yielding a total of 33 patients. 2 outcomes were selected for logistic regression analysis: final corrected distance visual acuity (CDVA) and need for surgical management. Results showed 33.3% of patients required surgery, 51.5% had their IFS resolve within 1 month or sooner, and 51.5% had final CDVA 20/25 or better. Higher presenting intraocular pressure (IOP) and duration of IFS ≤1 month was associated with higher odds of final CDVA 20/25 or better (adjusted odds ratio [aOR] 1.12, P = .04; aOR 7.71, P = .02, respectively). Endothelial cell dysfunction led to 17.55 greater odds for requiring surgical compared to medical management (aOR 0.36, P = .04). Presenting IOP and duration of IFS predicted final CDVA, while prior endothelial cell dysfunction predicted need for surgery.

Abstract
PURPOSE OF REVIEW Given the popularity of keratorefractive surgery, and an aging populous of patients who have undergone these procedures, there is an increasing need for updated management protocols. This is particularly relevant for patients with chronic progressive diseases such as glaucoma, due to the variety of related diagnostic and management challenges inherent to these diseases. Here, we will review the current literature to provide an update on the management of patients with glaucoma who are undergoing, or have had laser ablative refractive surgery. Preoperative testing and eligibility considerations, intraoperative factors, and postoperative observation and follow-up will be discussed. RECENT FINDINGS Intraoperative intraocular pressure (IOP) rise during flap creation is associated with low risk of acute complications, and furthermore do not appear to have significant long term effects. Modern technologies have improved our ability to determine accurate IOP after refractive surgery despite postoperative changes in corneal architecture. Furthermore, advances in structural imaging allow for earlier detection of even subtle glaucomatous nerve damage. SUMMARY Although glaucoma remains a relative contraindication to refractive surgery, it is a safe procedure for many patients with appropriate perioperative management and follow-up. Advancements in diagnostic modalities have allowed for earlier detection of glaucomatous disease, and subsequent earlier intervention when appropriate. Standardized diagnostic algorithms and rigorous perioperative assessment are critical to safe management of glaucoma patients undergoing refractive corneal surgery.

Abstract
Endothelial keratoplasty is now favored over full-thickness penetrating keratoplasty for corneal decompensation secondary to endothelial dysfunction. Although endothelial keratoplasty has evolved as surgeons strive to improve outcomes, fewer patients than expected achieve best corrected visual acuity of 20/20 despite healthy grafts and no ocular comorbidities. Reasons for this remain unclear, with theories including anterior stromal changes, differences in graft thickness and regularity, induced high-order aberrations, and the nature of the graft-host interface. Newer iterations of endothelial keratoplasty such as thin manual Descemet stripping endothelial keratoplasty, ultrathin automated Descemet stripping endothelial keratoplasty, and Descemet membrane endothelial keratoplasty have achieved rates of 20/20 acuity of approximately 50%, comparable to modern cataract surgery, and it may be that a ceiling exists, particularly in the older age group of patients. Establishing the relative contribution of the factors that determine visual quality following endothelial keratoplasty will help drive further innovation, optimizing visual and patient-reported outcomes while improving surgical efficacy and safety.
