purpose : to investigate tear film status after phacoemulsification surgery with temporal and supratemporal clear corneal incision in a cohort of patients with senile cataract methods : we enrolled sixty eight eyes of 68 patients with senile cataract requiring phacoemulsification in a prospective, cohort study. all patients undergone basic tear secretion test (btst), tear meniscus height (tmh),...

purpose: to compare clear corneal incision and scleral tunnel incision in terms of intraocular pressure (iop), post-operative inflammation, induced astigmatism, and corneal edema in phacoemulcification. methods: this non-controlled clinical trial was conducted on 78 eyes with senile cataract. a clear corneal incision was made in 40 eyes and a scleral tunnel incision was made in 38 eyes. all eye...

AIM To compare postoperative keratometric corneal refractive changes after phacoemulsification surgery between pre-incision and single stepped clear corneal incision techniques. PATIENTS AND METHODS This prospective clinical study included 40 eyes of 40 patients who underwent clear corneal cataract surgery. Twenty eyes were operated using pre-incision technique (Group A), and 20 eyes using si...

Purpose. To compare the surgically induced astigmatism from clear corneal and square posterior limbal incisions at the time of cataract surgery. Methods. Surgically induced astigmatism was calculated for a set of eyes after cataract surgery using a temporal 2.2 mm square posterior limbal incision. Results were compared to similar available data from surgeons using clear corneal incisions of sim...

Effects of incision angle in construction of clear corneal cataract incision are studied with optical coherence tomography (OCT). A stable incision angle range is found to be existent for single-planed, clear corneal cataract incisions. When well pressurized, incision angles within this stable range result in well-apposed incision edges that resist gapping while incision angles falling outside ...

An optimal clear corneal incision creates a self-sealing intrastomal tunnel. Variability in incision length may pose surgical difficulties for subsequent phacoemulsification. An incision that is too long may lead to challenges including decreased instrument mobility, decreased visibility due to corneal striae, stromal hydration, and a difficult angle of approach to the cataract. These sequelae ...

PURPOSE To examine the profile of clear corneal cataract incisions in the living eye using optical coherence tomography (OCT). SETTING Private practice, Eugene, Oregon, USA. METHODS The Zeiss Visante OCT anterior segment imaging system was used to study the profile of clear corneal cataract incisions, all in senior citizens. The OCT images of the operative eye were taken on the first postop...

BACKGROUND AND OBJECTIVE To compare the architecture of single plane self-sealing clear corneal incision (SP-CCI) and shallow grooved self-sealing clear corneal incision (SG-CCI) after cataract surgery using Fourier-domain optical coherence tomography (FD-OCT). PATIENTS AND METHODS An FD-OCT system with a corneal adaptor module was used to image the corneal incisions in radial sections in 44 ...
