Anterior segment optical coherence tomography evaluation and comparison of main clear corneal incisions in microcoaxial and biaxial cataract surgery

Abstract

Although closure was reliable in both groups, the microcoaxial group had slightly fewer undesirable effects on the incision site. Low postoperative IOP seemed to be a significant factor in problematic healing.

Healing changes in clear corneal cataract incisions evaluated using Fourier-domain optical coherence tomography

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] To our knowledge, this is the first study to assess the longterm architectural features of CCIs using OCT. We found 3 posterior wound changes, 2 of which were seen only in the first 3 months following surgery. Descemet detachment was seen in 37.1% of corneas 1 day postoperatively and in no eye imaged after 3 months.…”

“…However, they could also be attributable to differences in technique in imaging these incisions. Fourier-domain OCT was used in our study and the study by Can et al, 11 and spectral-domain OCT was used in all other studies.…”

“…In addition, OCT software allows measurement and quantification of architectural features. Using AS-OCT, [1][2][3][4][5][6][7][8][9][10][11][12][13] several studies have assessed the short-term (up to 1 month) architectural changes in CCIs after cataract surgery. However, we are unaware of studies evaluating the long-term changes that occur in clear corneal cataract incisions.…”

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

“…Technical developments now allow phacoemulsification to be performed using a biaxial or microcoaxial approach. 1,2 Recent advances in IOL technology and the use of cartridge systems allow IOL implantation in the capsular bag through small corneal incisions.…”

Optical coherence tomography studies of clear corneal incision wound architecture

“…Optical coherence tomography studies of clear corneal incision wound architecture I would like to congratulate Can et al 1 on their comparative study of the optical coherence tomography (OCT) appearance of clear corneal incisions (CCIs) in cataract surgery, particularly their demonstration of the detrimental effects of enlarging the wound at the end of surgery. It has been suggested that CCIs are most vulnerable in the immediate postoperative period, when they are susceptible to microleaks causing a decrease in intraocular pressure (IOP).…”
