Effect of ophthalmic Nd:YAG laser energy on intraocular lenses after posterior capsulotomy in normal dog eyes

Abstract: Both posterior lens capsules and IOLs were disrupted in an energy-dependent manner with minimal difference in number of capsulotomy sites or damage to the IOL between acrylic and PMMA IOLs. A therapeutic margin between capsulotomy threshold (2.6-2.7 mJ) and IOL damage threshold (4.9-5.7 mJ) was determined to reliably achieve capsulotomies with minimal IOL damage for both acrylic and PMMA IOLs in normal canine cadaver eyes.

“…The procedure is not performed without its own potential complications including damage to the IOL, intraocular pressure elevation, cystoid macular edema, retinal detachment, IOL luxation or endophthalmitis [59]. A recent study [61] evaluated the effect of Nd:YAG laser energy on PMMA and acrylic IOLs in normal canine cadaver eyes. They determined that there was a therapeutic margin between capsulotomy threshold (2.6-2.7 mJ) and IOL damage threshold (4.9-5.7 mJ) that reliably achieved capsulotomies with minimal IOL damage for both acrylic and PMMA IOLs [61].…”

This may pose a problem in dogs with hypermature cataracts or in those that develop dense posterior capsular changes due to PCO, wherein the capsule becomes excessively thickened and wrinkled.…”

“…Greater energy is therefore required to achieve a capsular hole, which may account for the greater incidence of post laser uveitis 10 . The requirement for greater energy levels also increases the potential for IOL damage 11 . Consequently, recent goals have been aimed at prevention of this common complication.…”

“…In a series of 33 dogs the success rate, as assessed by increased clarity of the lens capsule, was 75 % . The average canine PCO requires 75 bursts of 40 mJ each to open the capsule, while in humans only 8-10 bursts of 1-2 mJ are necessary [12,80] .…”
