Abstract
BackgroundIntraoperative IOLs clouding of several kinds of hydrophilic acrylic intraocular lenses (IOLs) have been reported due to temperature changes. This phenomenon reported previously occurred in cold countries and during the winter months. However, no clinical case was reported about trifocal IOL opacification during operation. We report a case in which acute opacification of the optical region occurred simultaneously when AT LISA tri 839mp(Carl Zeiss) was implanted into the eye.Case presentationA 79-year-old woman with a cortex and nucleus cataract was scheduled to undergo right eye phacoemulsification assisted by femtosecond technique. The trifocal lens (AT LISA tri 839mp), which is made of hydrophilic acrylic (25%) with hydrophobic surface properties, was chosen for implantation. As the IOL was implanted into the eye, it became cloudy immediately. Then it was replaced by another AT LISA tri 839mp, which was transferred from lens company outside, the same phenomenon was observed. These two lenses underwent the same temperature fluctuation from cold outside to operating room. Finally, a ZCB00 (Allergan) was implanted.ConclusionsThe acute intraoperative clouding of trifocal lens(AT LISA tri 839mp) results from fluctuation of temperature should be noticed.

Intraoperative Intraocular lens (IOL) clouding of several kinds of hydrophilic acrylic intraocular lenses (IOLs) have been reported due to temperature changes
The major hydrophilic acrylic intraocular lenses(IOLs) that have been reported on regarding postoperative opacification include Hydroview (Bausch& Lomb), SC60B-OUV (Medical Developmental Research, Inc.), ACRL-60 (Ophthalmed, LLC), Memory Lens (Ciba Vision), AquaSense (Ophthalmic Innovations International, Inc.), and Akreos Adapt AO (Bausch & Lomb) [1,2,3,4,5,6]
As soon as the optical region was implanted into the eye, it became cloudy (Fig. 2), and remained cloudy without alleviation (Fig. 3) for 1 h in vivo(Waiting for the second +18.5D AT LISA tri 839mp,we observed whether the clouding IOL would be clear)
Summary
The major hydrophilic acrylic intraocular lenses(IOLs) that have been reported on regarding postoperative opacification include Hydroview (Bausch& Lomb), SC60B-OUV (Medical Developmental Research, Inc.), ACRL-60 (Ophthalmed, LLC), Memory Lens (Ciba Vision), AquaSense (Ophthalmic Innovations International, Inc.), and Akreos Adapt AO (Bausch & Lomb) [1,2,3,4,5,6]. Case presentation To meet patient expectations of high-quality postoperative vision, including distant, medium, and near vision, a 79-year-old woman with a cortex and nucleus cataract was scheduled to undergo right eye phacoemulsification. In this patient, we routinely used perioperative regimen of mydriasis by tropicamide 4 times every 10 min, superficial anesthesia by proparacaine 4 times, Medical Sodium Hyaluronate Gel(17 mg/ml, Bausch& Lomb), and compound chloride perfusate. The IOL was removed using small incision on the sclera We try another AT LISA tri 839mp lens, which was transferred from local company outside, The temperature outside was about −3 °C. The IOL had been in the theater for about 10 min before
