Abstract Details

Purpose:

To study incidences of sticking haptic to the IOL optic surface after delivering the foldable hydrophilic intraocular lens into the capsular bag

Setting:

Medical Center of Medical Faculty, Y?ld?r?m Beyazit University, Bilkent, Ankara, Turkey

Methods:

Clinical reports of all cataract operation cases with a specific type of hydrophilic acrylic intraocular lens implantations, performed between February 2010-March 2012, were rewieved retrospectively. Cases in which persistent adhesion of a haptic of the IOL implant to the lens optic occured were identified. In these cases, techniques to release the stuck haptic, mean operational time required to tackle the stuck haptic, peroperative complications related to this adhesion, postoperative ophtalmological examination findings were evaluated.

Results:

This model of intraocular lenses were implanted via a cartridge filled with an ophthalmic viscosurgical device in 950 cases totally. In eight cases a strong adhesion, resistant to simple maneuvers for seperation, between optic and haptic was noted after intraocular lens unfolded intraocularly. In six cases this adhesion could only be released by help of a series of complex intraocular maneuvers using irrigation and aspiration canulas. In remaining two cases bimanual maneuvers using sinskey hooks and spatulas were used to release optic-haptic adhesion. During these surgical maneuvers, zonule dialysis, less than 30 degrees, occured in two cases. In postoperative ophthalmological examination, severe corneal edema, resolved completely after two weeks, observed in four cases. Best corrected visual acuity increased to 20/20 in all cases in postoperative first month.

Conclusions:

In some hydrophilic acrylic intraocular lens implantations, recalcitrant adhesions between optic and haptics rarely occured because of some unelucidated material pecularities. Many approaches exist on tackling these stuck haptics, but this maneuvers increase peroperative and postoperative complications. FINANCIAL DISCLOSURE?: No
