Warm Viscosurgical Device Technique to Facilitate Intraoperative Delivery and Unfolding of Hydrophobic Acrylic IOL
Purpose
To evaluate the safety and effectiveness of a warm viscoelastic technique in aiding the intraoperative delivery and unfolding of the enVista MX60 hydrophobic acrylic IOL (Bausch + Lomb) during cataract surgery.
Methods
A new warm viscoelastic technique was used to maintain a deep anterior chamber during phacoemulsification and implantation of the enVista MX60 IOL in a retrospective series of 100 eyes. Outcomes evaluated included surgical time, intraoperative complications, lens unfolding, ease of removal of the viscoelastic, and postoperative intraocular pressure (IOP).
Results
Intraocular delivery and unfolding of the IOL was facilitated by use of warm viscoelastic. Inadvertent flipping of the IOL and surgical times were reduced. The warm viscoelastic was easy to remove completely. There were no intraoperative complications. On postoperative day 1, IOPs were normal and no different than the IOPs in eyes that underwent phacoemulsification and implantation of the IOL without warm viscoelastic.
Conclusion
The warm viscoelastic technique is safe and effective in reducing surgical times and facilitating implantation of the enVista MX60 IOL and may also be utilized for similar hydrophobic acrylic intraocular lens implants.
