Recognizing and Managing Bullous Descemet Detachment Secondary to Accidental Hydroseparation During Phacoemulsification/Cataract Surgery by Relaxing Descemetotomy

Conclusions: Rarely stromal hydration performed with an irrigating cannula positioned too close to the posterior stroma can result in hydroseparation of DM creating BDD, seen intraoperatively as a fluid wave propagating across the posterior aspect of the cornea. Large folds, free mobility, and DM tear classically seen with rhegmatogenous Descemet detachment are not seen clinically or on ASOCT in BDD. Pneumodescemetopexy alone cannot resolve BDD because without a DM tear, SDF cannot evacuate. Combining relaxing Descemetotomy with pneumodescemetopexy allows SDF to drain internally and Descemet detachment to resolve. This technique has numerous advantages over classical venting incisions in terms of ease, preferable limbal location, larger incision size, absence of complications such as visual axis scars, irregular astigmatism, epithelial ingrowth, infectious keratitis, etc.

This study compared the best corrected visual acuity (BCVA), surgically induced astigmatism (SIA), endothelial cell loss, and patient satisfaction between corneal section phacoemulsification (CSP) and Blumenthal manual small incision cataract surgery (MSICS).MethodsIn this pragmatic study, following pre-operative assessment, patients made a choice to undergo either CSP or MSICS after the options were explained by the ophthalmologist. Pre- and post-operative (Day 1, 1-week, 6-weeks) refraction, keratometry and specular microscopy were performed. Subjective improvement in visual function was assessed before surgery and at 6-...

We present a case in which a different approach was used to treat an eye with dense cataract associated with an irregular failed full-thickness corneal graft. After cataract surgery, a foldable intraocular pinhole was implanted in the capsular bag to treat the irregular corneal astigmatism. Next, a Descemet membrane endothelial keratoplasty graft was used to improve transparency in the failed penetrating keratoplasty. This approach addressed the cataract, irregular cornea, and failed graft through a standard 2.2  mm clear corneal phacoemulsification incision, thus avoiding open-sky surgical time and expediting visual rehabilitation.

Authors: Schiano Lomoriello D, Savini G, Naeser K, Colabelli-Gisoldi RM, Bono V, Pocobelli A Abstract Purpose: To investigate the effectiveness of toric intraocular lenses (IOLs) for treating corneal astigmatism in patients with cataract and previous deep anterior lamellar keratoplasty (DALK). Setting: San Giovanni-Addolorata Hospital, Rome, Italy. Design: Prospective interventional case series. Methods: Patients undergoing cataract surgery after DALK for keratoconus were enrolled. Total corneal astigmatism (TCA) was assessed by a rotating Scheimpflug camera combined with Placido-disk corneal topography...

ConclusionsThe difference between means of pre-op astigmatism and residual astigmatism in the study group was significant at p = 0.001 with 95% CI −2.22 to −1.50. This significant difference was because of the toric IOL implantation.
