Unusual presentation of corneal laceration in a post-LASIK eye following blunt trauma.

PURPOSE: To report a case with full thickness corneal laceration behind the intact LASIK flap after blunt trauma. OBSERVATIONS: A 48-year-old man with a history of LASIK surgery was hit by a shovel. Slit-lamp examination showed 4+ corneal edema. The anterior chamber (AC) was deep and the Seidel test was negative. Uncorrected distance visual acuity (UDVA) was hand motion. A more accurate evaluation was performed with an anterior segment optical coherence tomography (OCT) and it was found that the paracentral corneal tissue was ruptured while the flap remained completely intact. Under the surgical procedure, the rupture site was sutured, and then the flap was replaced, and two U-shaped sutures were performed to ensure the flap stability. Three months after surgery, corrected distance visual acuity (CDVA) was 9/10 decimal with a manifest refraction of +1-3 x 60°. CONCLUSIONS AND IMPORTANCE: In a traumatic post-LASIK eye, the posterior part of the flap should be carefully evaluated. The role of the OCT device in the diagnosis and management of complication is also very valuable.

A Novel Approach to Treatment of Conjunctival Cyst Ablation Using Atmospheric Low-Temperature Plasma.

PURPOSE: Introducing a new technique to remove the conjunctival cyst using atmospheric low-temperature plasma (ALTP) and assessing its effectiveness. PATIENTS AND METHODS: Five eyes with conjunctival cysts were included in this study. The procedure was started by applying a plasma spot on the highest point of the cyst, and then other spots were spirally applied to the base of the cyst to debulk it. The conjunctival cysts were removed using the white handpiece of the plasma generator device (Plexr, GMV s.r.l Grottaferrata, Italy). Refraction, visual acuity, intraocular pressure (IOP), contrast sensitivity (CS), aberrometry, dry eye tests, and ocular surface disease index (OSDI) questionnaire were measured before, one and six months after treatment. RESULTS: The mean size of the cysts was 3.6 mm (range 2.1 to 4.8 mm). No intraoperative and postoperative complications were observed. Postoperative examinations showed that the patients' cysts were completely healed and recurrence did not occur. Significant changes in visual parameters, IOP, CS, aberrometry and dry eye tests were not observed in the follow-up periods after treatment compared to before. OSDI score decreased after cyst removal. CONCLUSION: Our recommended technique using ALTP can be used as a new approach to treating conjunctival cysts. This technique is a simple, office-based, minimally invasive, effective and inexpensive way to remove a cyst.
