astigmatism

5 things you missed at SECO 2017 in Atlanta
5 things you missed at SECO 2017 in AtlantaSECO 2017 has come to a close, but Optometry Times has you covered with things you may have missed while taking in a lecture, perusing the exhibit hall, or exploring Atlanta’s Centennial Park.
New wavefront indication enhances treatment for mixed astigmatismThe approved use of wavefront-guided technology for mixed astigmatism may help ophthalmologists to reach another potential group of patients.
My refractive surgery journey as surgeon and patientMy interest in refractive surgery started in 1976 when my good friend and fellow University of Southern California (USC) ophthalmology resident Rick Villaseñor returned from his course in keratomileusis surgery with Jose Barraquer in Bogota, Columbia.
At what amount of cylinder do you prescribe toric soft lenses?When do you move from a spherical to a toric contact lens? Let us know!
Multifocals show similar results but lower power offers better vision rangeBoth the Tecnis multifocal +2.75 D and +4.00 D IOLs had good visual results, but the +2.75 D IOL had a better range of vision across near, intermediate, and distance.
Exploring laser vision correction for myopia with/without astigmatismA prospective masked study enrolling eyes with low to moderate myopia with or without astigmatism found significantly better efficacy, safety, and predictability with wavefront-guided LASIK compared with small incision lenticule extraction (SMILE).
Addressing scleral lens clinical concernsWhile scleral lenses offer more stability than traditional lenses, there are still many controversies about their use that may give practitioners pause
Advances in femto provide better results, fewer complicationsAdvances in femtosecond laser assisted cataract surgery (FLACS) providing better results, fewer complications, and higher rates of patient satisfaction.
Toric trifocal IOL brings expanded range of functional vision to larger patient population
Toric trifocal IOL brings expanded range of functional vision to larger patient populationTrifocal IOLs can provide good uncorrected vision at near, intermediate, and far. Outcomes in a series of 30 patients show that a toric version of a trifocal IOL (AT Lisa tri 939MP, Carl Zeiss Meditec) delivers those benefits for patients with > 1 D of corneal astigmatism.
Corneal astigmatism independent of patient age at surgeryOptimal planning for correction of pre-existing corneal astigmatism at the time of cataract surgery should take into account an age-related, against-the-rule (ATR) shift.
