TLDR
The smallest incision group had the least surgically induced astigmatism and axial change, and all incision groups remained stable and had satisfactory clinical results.Abstract:
Purpose: To determine whether a small clear corneal temporal incision produces less surgically induced astigmatism than a larger incision. Methods: One hundred three consecutive cases of postoperative astigmatism after clear corneal incision cataract surgery were studied for a minimum of 1 year. Only self-sealing incisions from the temporal side were made as follows: 3.2 mm (Group A); 4.0 mm (Group B); 5.2 mm (Group C). We considered the amount and axes of the keratometric readings at different times as well as their course over time. Induced astigmatism was calculated using three methods. Axial changes were also analyzed. Results: Immediately after the surgery, there was a small, surgically induced, withthe-rule astigmatic shift in all groups, which in most cases decreased to near preoperative levels with time. One year postoperatively, mean induced astigmatism was 0.09 diopter (D) in Group A, 0.26 D in Group B, and 0.54 D in Group C. Most cases had minimal axial changes. In Group A, 86% had an axial change of fewer than 30 degrees; in Group B, 76%; and in Group C, 73%. Conclusion: The smallest incision group had the least surgically induced astigmatism and axial change. All incision groups remained stable and had satisfactory clinical results.read more

TL;DR: Improved surgical techniques for removing the anterior lens capsule have decreased the incidence of both intraoperative and postoperative capsular complications, and continual evolution of this technology promises to further improve patient outcomes after cataract surgery.

Limbal relaxing incisions versus on-axis incisions to reduce corneal astigmatism at the time of cataract surgery.
TL;DR: The amount of astigmatism reduction achieved at the intended meridian was significantly more favorable with the LRI technique, which remained consistent throughout the follow‐up period.

Astigmatic stabilization of 3.0 mm temporal clear corneal cataract incisions

TL;DR: The surgical method resulted in stable corneal curvature by 2 weeks after surgery at which time the patient is ready for final spectacle prescription and can be discharged from acute postoperative ophthalmologic care in the absence of complicating factors.

TL;DR: Cataract surgery using a horizontal clear corneal incision induced WTR astigmatism 6 weeks and 12 months postoperatively, and temporal incisions induced significantly lessAstigmatism than nasal incisions.

Astigmatism after small incision cataract surgery. A prospective, randomized, multicenter comparison of 4- and 6.5-mm incisions.
TL;DR: Subgroup analysis of the suturing technique showed that the technique of wound closure, as well as the wound size, influenced the induced astigmatism, however, the variability in the amount of induced cylinder was least with the 4.0-mm wound.

Induced astigmatism in small incision cataract surgery.
TL;DR: The use of smaller cataract incisions is thought to induce less astigmatism, resulting in a more stable refraction, and this results confirms an advantage of small incision surgery.

Calculation of the change in corneal astigmatism following cataract extraction.
TL;DR: Analysis of the surgically induced change in astigmatism using the calculations described in this paper will allow the surgeon to evaluate his own techniques and to maximize his potential for obtaining consistently good postoperative astigmatic results without the need for suture removal.

Small incisions to control astigmatism during cataract surgery.
TL;DR: It is concluded that the phacoemulsification procedure induced significantly less astigmatism and provided faster visual rehabilitation than the ECCE procedure, and the use of small diameter PMMA IOLs inserted through small incisions minimized surgically induced cylinder in a way comparable to theUse of foldable silicone implants, while maintaining good visual results with fewer postoperative complications.
