Endophthalmitis rates after implantation of the intraocular Collamer lens: Survey of users between 1998 and 2006

Abstract

An anonymous on-line survey was sent to 234 intraocular Collamer lens (ICL) (Staar Surgical) surgeons in 21 countries to determine how many of their ICL cases had been complicated by endophthalmitis between January 1998 and December 2006. A second questionnaire about the infection details and treatment outcome was sent to those who reported cases of endophthalmitis. Ninety-five (40%) surgeons responded to the survey. They had implanted 17954 ICLs during the study period. Three surgeons reported 1 case of endophthalmitis each, a rate of 0.0167% (95%) confidence interval 0 to 0.036%) or approximately 1 case of endophthalmitis per 6000 ICL implantations. Follow-up details were available in 2 cases. Staphylococcus epidermidis was cultured in both cases, and both were treated without loss of vision. Endophthalmitis may be less common after ICL implantation than after cataract surgery. Further studies are required to define the rate and prognosis for endophthalmitis after ICL implantation to assist in accurate preoperative patient counseling.

Posterior chamber collagen copolymer phakic intraocular lenses to correct myopia: Five-year follow-up

“…Several studies report its effectiveness in correcting myopia, [1][2][3][4][5] hyperopia, 6,7 and astigmatism [8][9][10] or in patients who may not be appropriate candidates for corneal reshaping procedures. [11][12][13][14] However, in addition to the risks of any intraocular surgery, 15 the main concerns with pIOL implantation relate to its long-term safety, including long-term endothelial cell loss, 16,17 pigmentary glaucoma, 18 pupillary block, 19,20 and cataract formation. 21 Although studies of pIOL implantation report acceptable complication and visual acuity loss rates, few studies have spanned more than 3 years to observe the long-term clinical and refractive outcomes.…”

Successful re-implantation of implantable collamer lens after management of post-ICL methicillin-resistantStaphylococcus epidermidisendophthalmitis

“…Conservative management in mild cases, with intracameral or intravitreal antibiotics, may result in optimal visual recovery 2 8–10. However, a pars plana vitrectomy may be needed in more fulminant cases with poor visual and anatomical outcomes 4–6…”

“…Endophthalmitis is a potentially sight-threatening complication with an incidence of around 1 case per 6000 after posterior chamber phakic IOL implantation 2. The management is similar to postsurgical endophthalmitis; however, a phakic IOL explantation may additionally be required in cases with dismal visual outcomes 3–6…”

Sequels after Implantation of Intraocular Collamer Lens

“…Allan et al [3] conducted an online survey of 234 surgeons in 21 countries to show how many of their ICL cases had been complicated by endophthalmitis between January 1998 and December 2006. During the study period, 3 surgeons reported 1 case of endophthalmitis each, a rate of 0.0167% or approximately 1 case of endophthalmitis per 6000 ICL implantations.…”
