PURPOSE To describe the safety and efficacy of removing posteriorly dislocated lens fragments with the use of intravitreal ultrasonic fragmentation through a limbal, clear cornea self-sealing incision. METHODS Patients presenting with posteriorly luxated nuclei were enrolled in this prospective case series. Preoperative examination included evaluation of the corneal endothelium by means of sp...

PURPOSE To compare a transconjunctival single-plane sclerocorneal incision with 2 tiny conjunctival cuts at both ends and a clear corneal incision (CCI) in cataract surgery. SETTING Department of Ophthalmology, Institute of Clinical Medicine, University of Tsukuba, Ibaraki, Japan. METHODS Patients having routine cataract surgery were randomly divided into 2 groups based on incision type; th...

PURPOSE To study the effect of small-incision cataract surgery on the optical aberrations of the cornea. METHODS Corneal topography was measured before and after cataract surgery on 70 eyes of 70 patients. Monofocal foldable IOLs were implanted after phacoemulsification through a clear-cornea, 3.5-mm incision without suture. Corneal aberrations, up to the fifth order and 6-mm pupil, were calc...

PURPOSE To compare the consistency of incision architecture utilizing a traditional diamond keratome and a newly designed diamond keratome. METHODS We used a traditional diamond keratome and newly designed diamond keratome to create clear corneal incisions in human cadaveric donor eyes. Three surgeons with varying levels of experience made 30 incisions with each keratome; and the wound archit...

Endothelial cell loss is a key indicator of the quality anterior segment surgery like cataract surgery. The amount and integrity corneal endothelial cells are two most essential factors determining transparency. Aim this study was to compare between superior scleral tunnel incision temporal clear for phacoemulsification. Prospective observational study. This prospective included 50 patients wit...

OBJECTIVE Clear corneal cataract incisions without sutures allow for rapid visual rehabilitation after phacoemulsification but might be associated with an increased risk of postoperative infection. The goal of this study was to examine in vitro dynamic changes in unhealed clear corneal cataract incisions that might adversely affect the risk of intraocular infection. DESIGN Laboratory investig...

PURPOSE To assess the relationship between corneal endothelial cell loss after phacoemulsification and the location of the clear corneal incision. METHODS A total of 92 patients (92 eyes) with senile cataracts who met the study criteria were included in this cross sectional study and underwent phacoemulsification. The incision site was determined based on the steep corneal meridian according ...
