“…Mean corneal astigmatism in our study (1.03±0.9) is similar to previous studies. [10][11][12][13][14] In our sample 63.24% of the eyes have less than 1 D astigmatism. This eyes may have benefit from techniques described above.…”

“…[6][7][8] Despite this techniques, toric IOL implantation seems very successful and predictable to correct moderate and especially high degree astigmatism. 9,10 With the widespread use of toric IOLs, the researchers needed to evaluate prevalence of astigmatism in their countries. Table 2 shows, comparison of the values between other studies and the current study.…”

“…Our method does not address the loss of the first set of ink marks used to compensate for globe cyclotorsion. New imaging techniques are being introduced using high-resolution preoperative image and intraoperative registration to guide T-IOL alignment without the need of preoperative ocular marking (Cha et al 2011;Ventura et al 2014). Another promising new technology to evaluate toric IOL alignment is the Optiwave Refractive Analysis (ORA) or intraoperative wavefront aberrometer (Ventura et al 2014).…”

“…Treatment of corneal astigmatism is an important factor in cataract surgery, since residual astigmatism may compromise a patient's uncorrected visual acuity after surgery. It has been estimated that 30% of patients with cataracts have more than 0.75 D of corneal astigmatism, that 22% have more than 1.50 D, and that 8% have more than 2.00 D [1]. Toric intraocular lenses (IOLs) are used to correct corneal astigmatism that coexists in patients undergoing cataract surgery.…”

Purpose. To develop a mobile app that allows capturing and editing of photographs, performs image transposition and projection of a protractor with 360° axis markings, and permits accurate visualization of programmed alignment for the positioning of toric intraocular lenses (IOLs). Methods. In this prospective case series study, a codesign methodology was chosen to develop the Eye Axis Check application. After app development, measurements were obtained and comparisons were made between manual marks and toric IOL alignment without and with the app in 30 eyes that had undergone cataract surgery with toric IOLs. The mobile app was made available to 15 ophthalmic surgeons in different cities to assess its usability. Results. The users approved the developed application for its ease of use and utility. The mean difference between the markings made manually and those made with the app was 1° (±2°; range: 0°–5°), and the mean difference between the IOL position and the assessment made by the app was 3° (±3°; range: 0°–12°). Upon comparison of the agreement between the app measurements and the manual measurements for the IOL angle, no significant differences were found, and an excellent concordance (0.997) and a strong positive linear correlation (0.995) were observed. Conclusion. A mobile app for preoperative planning and intraoperative toric IOL alignment was developed and revealed to be useful and easy to use.
