AstigmatismCylinderLASIKPRKRefractive surgeryPurposeTo compare the refractive outcomes of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) for myopic astigmatism of 3 diopters (D) or more.Study designRetrospective matched comparative study.Methods This study include consecutive ...
LASEK, LASIK safe, effective for myopic astigmatism.The article reports on the study that confirms the effectiveness of LASEK and LASIK for myopic astigmatism. According to Dr. Seyed Javad Hashemian, both techniques are safe, predictable, and effective for correcting low to moderate myopia and ...

Are You a Candidate for LASIK? Not everyone is a suitable candidate for LASIK. Ideal candidates are typically over 18 years old, have stable vision prescriptions for at least a year, and have healthy corneas. Certain conditions, such as severe dry eyes, high levels of astigmatism, or certain...
Although laser in situ keratomileusis (LASIK) enjoys a high success rate, postoperative residual or induced astigmatism may limit uncorrected visual acuity and cause starbursts and glare at night. Irregular astigmatism can also cause loss of best-corrected visual acuity, monocular diplopia, and ghosti...
astigmatism is shaped like an egg or the back of a spoon, rather than like a ping-pong ball.The ultra-precise lasers used for LASIK surgery can be programmed to reshape the cornea so the front surface of the eye is more symmetrical, thereby eliminating vision problems caused by astigmatism....
Evidence-Based Eye Care: July 2001 - Volume 2 - Issue 3 - pp 142-143 Clinical Studies LASIK for Myopia up to −11 D with up to −5 D of Astigmatism with the Summit Autonomous LADAR Vision Excimer Laser System Lane, Stephen S. MD ...
Methods: 51 high myopia eyes after SMILE and 49 high myopia eyes after FS-LASIK were enrolled and divided into two groups retrospectively. The OQAS and iTrace analyzer were used for optical quality inspection. Between the two groups the spherical equivalent (SE), astigmatism, uncorrected distant ...
We report a case of corneal ectasia detected 32 months after laser in situ keratomileusis (LASIK) for correction of −4.25 diopters (D) of myopia associated with –2.00 D of regular but slight asymmetric astigmatism. The patient retained stable visual acuity for 15 months postoperatively. The...
mesopic contrast sensitivity (CS) and higher order aberrations (HOAs) at 3 months after femtosecond-laser in situ keratomileusis (LASIK) (FS-LASIK), wave front-guided femtosecond LASIK (WF-LASIK), and femtosecond lenticule extraction (FLEx) for the correction of myopia and myopic astigmatism. ...
