Purpose To report the first case of acute angle closure due to a high-pressure Descemet membrane detachment following deep anterior lamellar keratoplasty (DALK) using the "big bubble" technique. Observations A 25-year-old man underwent DALK surgery for keratoconus using the "big bubble" technique in which an air bubble is injected in deep stroma to promote dissection of underlying Descemet me...

Purpose. The study aimed at evaluating the patients' characteristics, risk factors, complications, and visual outcome of traumatic wound dehiscence after keratoplasty. Patients and Methods. A retrospective case series that included 20 eyes of 20 patients who had undergone a previous keratoplasty procedure followed by traumatic wound dehiscence. Records of the selected patients were reviewed. Th...

purpose: to compare clinical outcomes following penetrating keratoplasty (pk) versus deep anterior lamellar keratoplasty (dalk) for keratoconic patients with vernal keratoconjunctivitis (vkc). methods: in this retrospective comparative study, the records of 69 keratoconic eyes with vkc that underwent pk (n=43, group 1) or dalk (n=26, group 2) were compiled. postoperative best-corrected visual a...

Material and Methods: Seventeen eyes of seventeen patients with advanced keratoconus who underwent DALK using Anwar's big bubble technique with1 year postoperative follow up were included in study. Uncorrected and corrected distant visual acuities (UDVA, CDVA, snellen acuity converted to logMAR notation), spherical equivalent SE (Diopters D)], refractive astigmatism [(Ast, D)], slit lamp biomic...

An interesting debate (not only in scientific meetings but also in personal conversations) has been taking place amongst ophthalmologists specialized on ocular surface and cornea. A few months ago, 2 articles in the Ophthalmology journal examined the characteristics that could determine the response of corneal tissue to 2 highly “fashionable” surgical techniques: Deep Anterior Lamellar Keratopl...

purpose: to compare the clinical and paraclinical outcomes following deep anterior lamellar keratoplasty (dalk) using frozen versus fresh corneas in patients with keratoconus. methods: in this prospective, comparative interventional study, 16 frozen and 19 fresh corneas were used during dalk in keratoconus patients. big bubble technique was used in all patients. the two groups were compared at ...
