contrast sensitivity comparison between two thin lenses, thinoptx® versus acrismart®, after micro incision cataract surgery
نویسندگان
چکیده
purpose : contrast sensitivity (cs) evaluation by sv–1000e chart in all spatial frequencies after micro incision cataract surgery (mics) and its comparison between two thin lenses after optical correction in natural and glare conditions methods : in this cross sectional study, 100 eyes having mics with dodick arc phacolaser system were evaluated. 50 thinoptx lenses and 50 acrismart lenses were randomly implanted in the eyes. uncorrected visual acuity (ucva), best spectacle corrected visual acuity (bscva), refractive error and cs, in all spatial frequencies were measured three months after surgery. csv-1000e chart with or without glare test was used for cs evaluation. normalized measures of cs were compared between two thin lenses with student’s t-test. results : cs profile was within the normal range in 52% of eyes and 48% of eyes had cs in lower than the normal range. the differences of cs in lower spatial frequencies [3 and 6 cycle/degree (c/d)] and higher spatial frequencies (12 and 18 c/d) between two lenses were not significant (p<0.449 and p<0.835, respectively). conclusion : after implantation of two lenses by mics, the cs in all spatial frequencies was similar. iranian journal of ophthalmology 200921(4):72-75 © 2009 by the iranian society of ophthalmology

Visual Outcomes After Cataract Surgery: Multifocal Versus Monofocal Intraocular Lenses.
PURPOSE To evaluate visual outcomes, spectacle independence, and quality of life among nonastigmatic and astigmatic patients who received AcrySof IQ ReSTOR toric or nontoric multifocal intraocular lenses (IOLs) (Alcon Laboratories, Fort Worth, TX) compared with those who received commercially available nontoric monofocal IOLs after bilateral cataract removal. METHODS This randomized, patient-...
متن کاملCorneal astigmatism after micro-incision cataract operation.
GOALS To evaluate the effect of micro-incision (2.2 mm) and small-incision (3.0 mm) coaxial phaco-emulsification on surgically induced astigmatism (SIA). METHODS Cataract patients (n = 60, 60 eyes) were randomized into two groups: 30 eyes in the 2.2-mm incision group, 30 eyes in the 3,0-mm group. Phaco-emulsification was followed by intraocular lens implantation via the Monarch II injector wi...

MATERIALS AND METHODS aprospective interventional study without randomization was carried out includin...
متن کاملChick feed technique versus standard chop technique in micro incision cataract surgery.
BACKGROUND The important factor for improving the cataract surgery is reduction in size of corneal incision. Small incision results in less induced astigmatism, and faster visual rehabilitation. METHODS An analysis of 100 eyes of 80 patients operated for phacoemulsification through micro incision by standard chop technique (50 eyes) in group-I, and chick feed technique (50 eyes) in group-II i...
