The purpose of the present study was to compare the IOP and wound architectures immediately after phacoemulsificaton surgery between eyes that underwent long-length CCI (more than 1.75mm) and eyes that underwent short-length CCI (less than 1.75 mm.)

1) Longitudinal changes in intraocular pressure (IOP) using rebound tonometer before surgery, at the end of surgery (adjusted in a range between 15 and 25 mmHg); and at 30, 60, 120, 180 minutes, and 24 hours after surgery
2) Wound architectural features and wound length at 60 minutes after surgery using the anterior segment-optical coherence tomography (AS-OCT)
3) Wound leakage at 60 minutes after surgery examined using the Seidel test
4) Flare intensity at 60 minutes after surgery determined using the flare meter

This study was an exploratory study to compare the IOP and wound architectures between eyes with long CCI and eyes with short CCI, conducted between January and December, 2017 at the Hayashi Eye Hospital. A clinical research coordinator screened all consecutive patients scheduled for admitting the Hayashi Eye Hospital to undergo bilateral phacoemulsification and implantation of a single-piece acrylic intraocular lens (IOL).
eyes with any pathology of the cornea, macula, and optic nerve; eyes with lens nucleus harder than grade 4 according to the Lens Opacities Classification System III;14 eyes with a possible zonular dehiscence, a history of ocular inflammation or surgery; eyes with poor mydriasis smaller than 4.5 mm; patient refusal; and any anticipated difficulties with examination
