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.
CONCLUSION: Corneal shape and astigmatic changes were comparable between groups at 8 weeks postoperatively, although the changes were greater after nasal CCI than after temporal CCI in the early postoperative periods, indicating that nasal or temporal CCI can be selected based on the surgeon's preference.

CONCLUSION: Intraoperative digital marker system is associated with better TIOL alignment accuracy and better reproducibility than the manual ink-marking method. PMID: 29685740 [PubMed - as supplied by publisher]
CONCLUSION: This is the first study comparing the low- versus medium-power toric IOLs, the most widely used. This study suggests very good refractive results both with low- and medium-power toric IOLs with a single surgical procedure. PMID: 29685737 [PubMed - as supplied by publisher]
nörs D Abstract PURPOSE: To assess agreement of a swept source-optical coherence tomography (SS-OCT) based Biometer with a standard IOLMaster device and Scheimpflug Imaging (SI) to acquire keratometric measurements in cataract patients. METHODS: In this prospective comparative study, 101 eyes of 101 cataract surgery candidates, aged 24-81 years, were sequentially examined using three devices. Keratometry values at the flat (K1) and steep (K2) axis, mean corneal power (Km) and magnitude of corneal astigmatism as well as J0 and J45 vectoral components of astigmatism obtained with the SS-OCT based biom...
Conclusion: This study provides the distribution of astigmatism axis and power for cataract patients in age subsets from Turkey.
A 77-year-old man had cataract surgery in the left eye in March 2017. A toric intraocular lens (IOL) was implanted because of astigmatism. The postoperative meridian of the IOL was located nearly exactly in the planned meridian, which was controlled 1 week later with ray-tracing aberrometry (iTrace) and the smartphone application Axis Assistant. The referring ophthalmologist proceeded directly with a neodymium:YAG (Nd:YAG) laser posterior capsulotomy in his own office, after which the meridian of the implanted toric IOL was rotated more than 1 15 degrees.
Conclusion: Consideration of only corneal front keratometric values for toric lens calculation may lead to postoperative undercorrection of astigmatism. The prediction of postoperative refractive outcome can be improved by using appropriate methods of adjustment in order to take PCA into account. PMID: 29545950 [PubMed]
It has been shown that approximately 30% of patients undergoing cataract surgery have corneal astigmatism of more than 0.75 diopters (D).1 Postoperative residual astigmatism decreases unaided visual acuity and quality of vision.2 A better understanding of the effect of posterior corneal astigmatism3 and the availability of more accurate toric intraocular lens (IOL) predictions have improved the ability to correct astigmatism with toric IOLs during cataract surgery, even in patients with low preexisting cylinder.4 Toric IOLs need to be positioned accurately on the intended meridian to have
To assess the accuracy of toric intraocular lens (IOL) power calculations of a new algorithm that incorporates the effect of posterior corneal astigmatism (PCA).
Although the incidence of epithelial ingrowth after LASIK decreased after the introduction of the femtosecond laser, incidental cases still might occur. The present case had a history of 7 previous treatment attempts. We do not know the removal techniques that were used in the past; however, it appears as though the visual outcome, despite the irregular astigmatism, was sufficiently satisfying the patient because he did not seek advice in the last 15 years. Because the patient's UDVA was still 20/25 and the major complaint is a red eye that seems to respond favorably to corticosteroid topical treatment, we decided to proce...
