“…In order to achieve an excellent visual acuity, the effect of astigmatism on the postoperative vision has to minimize. Burgansky et al have reported an increase in astigmatism with an increase in the incision size [6]. A pre-existing astigmatism can be neutralized by changing the site of the incision When the incision is located superiorly, both the gravity and the blinking of eyelid tend to create a drag on the incision.…”

“…This is the reason why the temporal approach is the best site to minimize induced astigmatism [19,25]. Furthermore, Burgansky et al [27] have studied the relationship between the size of the incision and the mean value of induced astigmatism. A 6 mm incision induced a mean astigmatism of 0.6 ± 0.3 D. Our results are close to that forecast.…”

Introduction: Cataract surgery is experiencing progress and adaptations in recent years with the aim to obtain better anatomical and functional results. Extraction of cataract by phacoemulsification has become a gold standard with its multiple variants. In developing countries, the cataract surgery by manual and sutureless small incision technique (MSICS) is increasingly practiced. The aim of this study is to assess astigmatism before and after cataract surgery by MSICS.

“…Temporal approach has been reported to result in smaller SIA than superior approach [12]. Small incisions (6 mm) induced the smallest SIA when compared with medium (6.5 mm) and large (7 mm) incisions [13]. The chevron shaped incision has also been reported to give minimal SIA when compared with straight and frown incisions [14].…”

The aim of the study was to report postoperative corneal and surgically induced astigmatism (SIA) in patients with preoperative against-the-rule (ATR) astigmatism who underwent superior approach manual small incision cataract surgery (MSICS). 58 eyes of 58 cataract patients with preoperative ATR astigmatism were involved in this study. All patients had operable cataracts and underwent superior approach MSICS. Keratometric (K) readings were taken prior to surgery and at 12 weeks after surgery. Centroid values of SIA, preoperative astigmatism, and postoperative astigmatism were calculated using Cartesian coordinates based analysis. Wilcoxon signed rank test was used to compute statistical significance between mean preoperative and postoperative corneal astigmatism. Cohen's d was used as effect size measure. Centroid values of 1.42 D × 179, 2.48 D × 0, and 1.07 D × 1 were recorded, respectively, for preoperative astigmatism, postoperative astigmatism, and SIA. Wilcoxon signed rank test indicated that mean ± SD postoperative corneal astigmatism (2.80 ± 1.40 D) was statistically significantly greater than preoperative corneal astigmatism (1.49 ± 1.34 D), Z = −6.263, p < 0.0001. A high Cohen's d of 1.32 was found. Our results suggest statistical and clinically significant greater postoperative corneal astigmatism than preoperative corneal astigmatism for ATR astigmatism cataract patients who underwent superior approach MSICS.

Minimal astigmatism after sutureless planned extracapsular cataract extraction

Abstract: Enlarging the size of the chevron incision up to 7.0 mm resulted in a small increase in induced astigmatism. The enlarged incision simplified the operative technique.
