Abstract

Aim To evaluate the effect of temperature on the restoration of the optical properties of hydrophobic acrylic intraocular lenses (IOLs) after ejection through a cartridge into a temperature-controlled water chamber. Methods Acrylic IOLs (SA60AT; iSert 251; W-60; X-70; and VA-70AD) were loaded into a cartridge with viscoelastic material and ejected into a water chamber at 24°C or 34°C. A wavefront analyser was used to measure the spherical and cylindrical powers, and the higher-order aberrations of the optics of the IOLs. The time to restore the cylindrical power to within 0.1 dioptres of the baseline power was determined. Results Surface irregularities of the IOLs after ejection were detected in the dioptric power maps but not in the higher-order aberration maps. The cylindrical power and the astigmatic and coma aberrations recovered immediately at 34°C but were delayed at 24°C. The restoration time of all IOLs at 24°C was significantly longer than that at 34°C ( p
