Abstract Background: To analyze and compare the clinical results of toric intraocular lens (IOL) and monofocal IOL implantation when the target refraction value is determined -3 diopter (D) in cataract patients with corneal astigmatism >1.5 diopters (D).Methods: We performed a retrospective chart review for patients with corneal astigmatism >1.5D who underwent cataract surgery and their target refraction is determined -3D. 100 eyes (100 patients; monofocal IOL, 60; toric IOL, 40) were enrolled in the current study. Near and distant uncorrected visual acuity (UCVA), corrected VA, spherical equivalent and refractive, corneal astigmatism were evaluated before and after surgery.Results: The near UCVA of the toric IOL group (0.26±0.33) after cataract surgery was significantly better than that of the monofocal IOL group (0.48±0.32) (p=0.030). The distant UCVA of the toric IOL group (0.38 ± 0.14) was also significantly better than that of the monofocal IOL group (0.55 ± 0.22) (p = 0.026). There were no significant intergroup differences in postoperative best-corrected visual acuity (p = 0.710) and mean spherical equivalent (p = 0.465). In the toric IOL group, postoperative refractive astigmatism was -0.80 ± 0.46D and postoperative corneal astigmatism was -1.50 ± 0.62D, whereas the corresponding values in the monofocal IOL group were -1.65 ± 0.77D and -1.45 ± 0.64D; residual refractive astigmatism was significantly lower with toric IOL implantation compared with monofocal IOL implantation (p = 0.001). Conclusions: When myopic refraction such as -3D was determined as the target power in patients with corneal astigmatism, toric IOL implantation led to excellent improvement in both near and distant UCVA.

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.

Purpose To evaluate the outcomes of deep anterior lamellar keratoplasty (DALK) followed by phacoemulsification and toric intraocular lens (IOL) implantation for the treatment of concomitant stromal disease and cataract. Methods In this retrospective non-comparative interventional case series, ten eyes affected by stromal disease and cataract underwent DALK followed by phacoemulsification with toric IOL implantation after a minimum period of 5 months from complete suture removal. In each case, topographic astigmatism, refraction, visual acuity, and endothelial cell density were recorded before DALK and 1, 6, and 12 months after cataract surgery. In addition, IOL rotation was evaluated using anterior segment optical coherence tomography. Results Big-bubble DALK was performed in all eyes but one that received manual dissection. Topographic astigmatism averaged 5.6 ± 2.2 diopters (D) after suture removal; refractive astigmatism decreased to 0.55 ± 0.61 D as early as one month after cataract surgery and did not change substantially throughout the follow-up period. In all patients, one month after phacoemulsification uncorrected and best spectacle-corrected visual acuity were, respectively, ≥20/40 and ≥20/25 with a residual spherical equivalent of 0.00 ± 0.84 D. At the latest follow-up visit, in all cases the IOL rotation was ≤5 degrees from the intended position and the endothelial cell loss within 8.5%. No complications were recorded. Conclusions DALK followed by phacoemulsification with toric IOL implantation optimizes visual and refractive outcomes in patients with concomitant stromal disease and cataract. In comparison with a combined procedure, the sequential approach offers better predictability of the postoperative refraction in the absence of an increased risk of complications.
