Finding a fix for irregular astigmatism after PK Transepithelial topography-guided PRK can help correct irregular astigmatism after penetrating keratoplasty.
Small-aperture IOL offers advantages over other presbyopia lenses
Small-aperture IOL offers advantages over other presbyopia lensesA new small-aperture intraocular lens (IOL) extends patients’ depth of focus as well as multifocal IOLs with fewer dysphotopsias, researchers say.
ARMOR surveillance study update gives current insights on antibiotic resistance for clinical ocular isolatesThe most recent analyses of data from the ARMOR (Antibiotic Resistance Monitoring in Ocular micRoorganisms) Surveillance Program can guide clinicians choosing antibiotic therapy for initial empiric therapy and infection prophylaxis. The information also reinforces the importance of prudent antibiotic prescribing to limit the development of bacterial resistance to existing options, according to Penny Asbell, MD.
Managing residual astigmatism after toric IOL surgeryResidual astigmatism is not uncommon after toric IOL implantation. Depending on its cause and magnitude, lens reorientation may be a good solution.
Study finds advantages using trifocal IOL to correct presbyopiaA 4-year study following trifocal IOL implantation (AT LISA tri 839MP, Carl Zeiss Meditec) found that the lens provided good distance, near, and intermediate visual acuity. The lens also improved patient quality of vision with better diffraction and less reduction in contrast sensitivity.
Exploring wider role for premium IOL implantation in glaucoma patientsWhen it comes to recommending a premium IOL, a patient’s glaucoma is only one factor to consider. Just like any other patient planning cataract surgery, visual needs and preferences for/against glasses are also important factors.
Taking on surgery in HSV patients
Taking on surgery in HSV patientsCataract and refractive surgeons should use prophylaxis to avoid reactivation of the herpes simplex virus (HSV) in patients with a history of infection with this virus, according to Elizabeth Yeu, MD.
Scleral implant for presbyopia making accommodative gains
Scleral implant for presbyopia making accommodative gainsImplantation of an investigational device for presbyopia resulted in a minimal 2-line increase in distance-corrected near visual acuity and an actual reduction in the amount of near add needed over time, show findings from a single-center, subgroup analysis.
Deeper implantation depth for inlay may enhance visual performanceA comparative analysis suggests placement of a cornea inlay (Kamra, AcuFocus) has improved patient satisfaction, refractive stability, and visual results when placed at 250 μm or deeper in the cornea. Shallower implantation depths may be more prone to refractive instability and lower patient satisfaction.
PiXL appears promising for low myopiaThe use of epi-on photorefractive intrastromal cross linking reduced myopia by about 0.25 D in a small study; In a high-oxygen group, the effect averaged 1.25 D.
