    Predictability of Existing IOL Formulas After Cataract Surgery in Patients with a Previous History of Radial Keratotomy: A Retrospective Cohort Study and Literature Review

    During the 1970s and 1980s, radial keratotomy (RK), a refractive surgical procedure that involves making radial incisions in the cornea, emerged as a widely adopted surgical solution for myopia and astigmatism [ 1 ]. However, the refractive results …

    Cataract surgery astigmatism incisional management. Manual relaxing incision versus femtosecond laser-assisted arcuate keratotomy. A systematic review

    The classic goal of cataract surgery is to achieve acceptable uncorrected distance visual acuity (UDVA) after intraocular lens (IOL) implantation. Mean corneal astigmatism in age-related cataract surgery is approximately 1 diopters (D) [ 1 ]. The …

    Refractive outcomes of femtosecond laser-assisted cataract surgery with arcuate keratotomy and standard phacoemulsification with toric intraocular lens implantation

    Cataract surgery has recently been considered a type of refractive surgery. An increasing number of patients started demanding for better visual quality rather than just a safe cataract surgery. Postoperative residual astigmatism is one of the …

    Astigmatic correction of simultaneous femtosecond laser-assisted cataract surgery (FLACS) with intrastromal arcuate keratotomy (ISAK) versus Toric intraocular Lens Impantation with conventional phacoemulsification

    A significant number of patients undergoing cataract surgery tend to have a varying degree of corneal astigmatism [ 1 , 2 ]. Approximately, a third of cataract patients have more than 1.25 diopters (D) of preexisting corneal astigmatism, whereas …

    Comparison of the accuracy of three intraocular lens power calculation formulas in cataract patients with prior radial keratotomy

    Myopia is the most common cause of distant visual impairment [ 1 ]. The prevalence of myopia has skyrocketed in the past few decades, especially in China [ 2 ]. Corneal refractive surgery is an effective way to correct adult myopia [ 3 ]. Radial …

    Descemet membrane endothelial keratoplasty in a patient with iris-fixated intraocular lens and prior radial keratotomy: a case report

    Descemet membrane endothelial keratoplasty (DMEK) is a well-established method of corneal transplantation for the treatment of endothelial dysfunction in Fuchs dystrophy [ 1 ]. Radial keratotomy (RK) is a method of refractive surgery historically …

    Lensectomy after radial keratotomy: 1-year follow-up

    Radial keratotomy (RK) was introduced around 1970, and it was the most common surgery for 20 years, when the corneal laser surgery became more popular. As it was reported, the main postoperative complications after RK were diurnal fluctuations …

    Two-year outcomes after full-thickness astigmatic keratotomy combined with small-incision lenticule extraction for high astigmatism

    Small-incision lenticule extraction (SMILE) is a flapless, all-femtosecond laser-based technique for correcting myopia and myopic astigmatism, which has gained widespread acceptance due to its good predictability, safety, and efficacy [ 1 – 3 ].

    Corneal hysteresis in post-radial keratotomy primary open-angle glaucoma

    Corneal hysteresis (CH) is a corneal biomechanical property, best described as viscoelasticity, which is measured by the ocular response analyzer (ORA, Reichert, Depew, NY). Corneal hysteresis may approximate the tissue properties of the lamina …

    Vector analysis of femtosecond laser-assisted astigmatic keratotomy after deep anterior lamellar keratoplasty and penetrating keratoplasty

    Postoperative astigmatism may contribute significantly to poor visual outcome in an otherwise successful keratoplasty procedure. The etiology of post-keratoplasty astigmatism includes intraoperative causes such as dull, tilted, or eccentric …

    Correction of hyperopia with astigmatism following radial keratotomy with daily disposable plus spherical contact lens: a case report

    Radial keratotomy (RK) is performed using radial incisions in the corneal stroma, producing a wound that is associated with midperipheral bulging of the cornea, compensatory central corneal flattening, and decreased refractive power. For this …

    Evaluation of the effectiveness of combined femtosecond laser-assisted cataract surgery and femtosecond laser astigmatic keratotomy in improving post-operative visual outcomes

    Modern cataract surgery has gradually evolved into a precise science, both for restoring visual acuity and for achieving emmetropia. Between 18 and 25% of patients undergoing cataract surgery exhibit > 1.5 diopters (D) of corneal astigmatism; …
