Nearly 60% were hyperopes, from which more than two thirds required an optical correction. Over or under-corrected myopia and uncorrected astigmatism were uncommon. Convergence insufficiency was found in 80%, and only a few ophthalmologic pathologies were diagnosed.Conclusion Many students have vision...
To evaluate clinical outcomes and visual quality 3 months after mini-monovision (spherical equivalent [SE] between − 0.25 D and − 0.50 D) femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for correction of high myopia in patients with presbyopia. Methods Patients who had mi...
Blurry vision, glare, and poor night vision are typical symptoms of cataracts. WebMD explains the condition with pictures including the causes, treatment options, and recovery.
Astigmatism Track 14:Uveitis Scleritis & Intraocular Inflammation Uveitis, scleritis, and intraocular inflammation are diverse conditions involving inflammation within the eye, each requiring a tailored approach to diagnosis and management to preserve vision and manage underlying systemic conditions effectively...
Inclusion criteria were as fol- lows: (1) age range between 18 and 45 years; (2) spheri- cal diopters of -0.5 D ~ -10 D, and astigmatism diopters no greater than 5 D; (3) corrected distant visual acuity (CDVA) ≥ 20/25; (4) stable refractive status for at least 2 years...
Anisometropia was defined as a difference in spherical equivalent between the two eyes of ≥ 0.50 Diopters (D), or a difference of astigmatism in any meridian ≥ 1.50 D56. Initial visual acuity was measured using an M&S logMAR chart. Inclusion criteria were: (i) presence of ...
Symptoms Postoperatively may have decreased vision (due to undercorrection, overcorrection, irregular astigmatism, or haze), fluctuating vision, difficulty with night vision, halos, glare, starbursts, ghost images, double vision, and variable discomfort (ranging from foreign body sensation to moderate ...
Both AT LISA TRI 839MP and AT LISA TRI TORIC 939MP (for significant regular astigmatism) IOLs are designed for aphakia correction after crystalline lens removal in eyes with senile cataract and any other forms of cataract. They are also indicated for presbyopia correction for patients with and ...
decreased from 45.4% in the total population to 17.3% in those not visually impaired. Pterygium impact on visual acuity in less usual and it is associated with high levels of astigmatism secondary to lesions greater than 3 mm16. Cataract, on the other hand, progressively decreases visual acuity...
binocular increments74. Nevertheless, a binocular advantage is preserved with more distant flankers up to about four times77. No binocular summation of collinear facilitation at a target-to-flanker distance of 3λ was recently found in both controls and subjects that presented oblique astigmatism76....
