Purpose
To investigate microcoaxial and clear corneal
incision (CCI) architecture in the postoperative
period using non-contact anterior segment optical
coherence tomography (Visante OCT ,Carl Zeiss)
3
Methods

• Prospective study
• 30 patients submitted to phaco
• Incision
• Microcoaxial 2.20 mm width (15 eyes)
• Clear corneal 2.75 mm width (15 eyes)
• IOL implantation
• Monarch injector
• Cartridge C

4
Methods

• Postoperative evaluation
• 1st day, 1st and 3rd months
• Slitlamp examination
• Seidel test
• IOP measurement
• Visante OCT
• Incision architecture
• Configuration
• Coaptation
• Stability

5
Results
No Descemets Detachment was observed at
slitlamp examination

Conclusions

• Visante OCT analysis of Microcoaxial and
  Clear Corneal Incision post phaco showed
• a higher percentage of Descemets Detachment in
  the Microcoaxial group at the 1st postoperative
  day
• that localized detachment of Descemets membrane
  may be more common than observed with slit-lamp
  microscopy
• different incisions' configurations between the
  two groups with no difference regarding proper
  coaptation and stability.
