Many surgeons consistently obtain excellent results with both of these strategies. 3) Two-stage procedure with excimer laser ablation. A third strategy for astigmatism management is to correct astigmatism postoperatively with an excimer laser. In appropriate candidates excimer ablation is safe and highly effective. An advantage of this approach is that residual spherical error can also be addressed by the ablation further refining the refractive outcome. Relative to the other strategies, cost remains the primary barrier to more widespread adoption of this approach. 4) Placement of surgical wound along steep axis of astigmatism. Small amounts of astigmatism can be managed by placing the surgical wound to coincide with the steep axis of astigmatism.
Click here to see a video of toric iol marking and placement. Drawbacks of the toric iol include its cost and the potential for instability of the corneal astigmatism or possible rotation of the lens in the years following surgery. Pineda studied the cost of the toric iol over a patient s life and determined that it may actually save money by reducing spectacle and contact lens expenditures (Pineda 2010). Corneal topography can change over time, raising the question of whether an axis shift down the road. In a young individual, a patient with keratoconus, or a post keratoplasty patient could turn the cylindrical component of the iol correction into a liability. One might be reluctant to implant a toric intraocular lens in a patient with a traumatic cataract, pseudoexfoliation syndrome, retinitis pigmentosa, or any other condition predisposing to loose zonules. Irregular astigmatism is not corrected with a toric lens and the toric iol can make placement of a contact lens to treat the irregular astigmatism difficult. Two recent studies have compared toric intraocular lens placement to peripheral corneal relaxing incisions for correction of astigmatism during cataract surgery. One study by poll, et al found the two strategies to yield comparable results with mild-to-moderate astigmstism (Poll 2011). The toric iol was favored for higher degrees of astigmatism. In a second study, mask mingo-botin, et al found that toric iol implantation was more effective and predictable between.00 and.00 diopters of preexisting astigmatism (Mingo-bot n 2010).
, and more recently with the femtosecond laser. Lris are a great option in patients with pre-existing astigmatism who desire presbyopia correction with a multifocal or accommodating iol as toric versions of these lenses are not fda-approved at present. Lris should be used with caution in patients with corneal ectasia, peripheral thinning, and advanced dry eye especially when associated with rheumatoid disease. 2) Toric intraocular lens. The first toric intraocular lens model was approved by the fda in 1998. Widespread use of toric iols would not come until later, however, with approval of a foldable toric iol in September 2005. Toric iols have the advantage of being able to correct large amounts of astigmatism. The most common toric iol used in the us is the single piece acrylic (SPA) design, which is more stable than the earlier silicon plate haptic models (Chang 1998, 2009, 2003). Alcon has published a web site for their toric iol calculation which is very useful and takes into account induced astigmatism from the wound ( m ).

During the what's preoperative visit the patient indicated his desire for spectacle independence following surgery. Astigmatism Options with Cataract Surgery, the surgeon has a number of options for the interaoperative management of astigmatism, including: Relaxing incisions, toric intraocular lens. Two-stage procedure with excimer laser ablation. Placement of surgical wound along steep axis of astigmatism. Options for astigmatic management around the time of cataract surgery, advantages and disadvantages: 1 r elaxing, i ncisions, peripheral corneal relaxing incisions (pcri) or the slightly more peripheral limbal relaxing incisions (LRIs) can flatten astigmatism as an adjunct to cataract surgery (Osher 1984, budak 1998). Lri's have been demonstrated bicarbonaat to predictably alter the corneal curvature by flattening the cornea in the meridian in which they are placed and allowing for a commensurate amount of steepening 90 degrees away. A number of nomograms are available to determine the arc length and number of incisions for a certain amount and axis of astigmatism, such as the donnenfeld nomogram ( m ). In addition to the degree of astigmatic correction desired, nomograms often take into account age, the distance the incisions are placed from the limbus, and corneal thickness.

Considerations for Astigmatism Management, june 10, 2011, introduction. Patient expectations for cataract surgery have increased significantly over the past several decades as surgeons have transitioned from standard extracapsular techniques to clear-cornea phacoemulsification. In addition to short operating times, topical anesthesia, and a sutureless procedure, patients increasingly expect spectacle independence following cataract extraction. In this dior tutorial we present the case of a 59-year-old male with a visually-significant cataract and consider the intraoperative management of astigmatism in a representative case of an individual with small-to-moderate cylindrical error. Presbyopia correction is discussed separately in a tutorial entitiled "Intraocular lenses for presbyopia " by, tim Johnson, md, phD. Case, a 59-year-old male presents with a visually significant cataract on the left. Preoperative manifest refraction: OD: -1.50 sphere, os: -1.50.75 x 110. Preoperative best-corrected visual acuity, od: 20/20, os: 20/50.
