Early changes in corneal edema following torsional phacoemulsification using anterior segment optical coherence tomography and Scheimpflug photography

Abstract

The micro-coaxial 2.2 mm incision may incur slightly less damage than the 2.8 mm standard incision in the context of torsional phacoemulsification. Observation of corneal morphology and damage using AS-OCT and Pentacam can be helpful in the evaluation and quantification of fine corneal edema.

Endothelial cell loss: Biaxial small-incision torsional phacoemulsification versus biaxial small-incision longitudinal phacoemulsification

“…Endothelial cells play a vital role in maintaining corneal transparency. 27 There is a close relationship between corneal edema and ECD after phacoemulsification. 28 Furthermore, edema formation in the corneal matrix layer due to intraoperative heating can also cause corneal edema.…”

“…28 Furthermore, edema formation in the corneal matrix layer due to intraoperative heating can also cause corneal edema. 27 A high balanced salt solution volume in the longitudinal method may be a reason for excessive corneal edema. 8 On the first day after surgery, the CCT could not be measured in a significant number of patients in the longitudinal group and the torsional group because of excessive edema.…”

Effect of intraocular lens insertion speed on surgical wound structure

“…Postoperative wound structure was estimated using a 3-dimensional OCT system (OCT-1000 Mark3, Topcon Corp.) with the anterior picture mode. The OCT findings were determined using the method described by Li et al 8 In brief, 40 slice photographs were taken in each eye. The number of photographs that showed signs of Descemet detachment, endothelial gap, or bulge was then counted.…”

Different-sized incisions for phacoemulsification in age-related cataract

“…One trial was conducted in Bosnia and Herzegovina (Musanovic 2012), 13 trials in China (Hui 2016; Li 2016; Lin 2013; Luo 2012; Mao 2008; Shan 2016; Shi 2013; Wang 2009; Yao 2008; Yao 2011; Yu 2016; Zhang 2014; Zhu 2014), one trial in France (Febbraro 2015), one trial in India (Vasavada 2013a), one trial in Italy (Mastropasqua 2011), five trials in Korea (Hwang 2008; Hwang 2016; Jeong 2013; Li 2011; Moon 2011), two trials in Spain (Capella 2010; Morcillo-Laiz 2009), one trial in Switzerland (Dosso 2008), and one trial in Turkey (Can 2010). …”

“…Five trials did not report the type of IOL inserted (Can 2010; Li 2011; Musanovic 2012; Shan 2016; Zhu 2014). …”
