BACKGROUND: Phakic IOLs are currently under clinical investigation for the correction of high myopia with acceptable postoperative refractive results. Although daytime vision is usually very good some patients complain of visual disturbances, described as glare and halos, during the night time, leading to difficulties in driving vehicles. PATIENTS AND METHODS: The quality of vision after phakic IOL surgery was investigated pre- and postoperatively using various tests for objective measurements of glare and halo in 40 myopic eyes (-9.0 to -20.0 D). Based on the implanted phakic IOL, eyes were divided into 4 groups of 10 eyes each where an Artisan 5.0 was implanted, an Artisan 6.0, a NuVita, and an ICL. RESULTS: All patients were happy with the postoperative refractive outcome and during daytime no visual discomfort was reported. In contrast, most patients reported visual disturbances during dim light conditions and at night time, described as glare and halos. The objective measurements showed in most eyes increased glare and halos which was most prominent in eyes with an ICL, followed by the NuVita IOL. In contrast, patients with an Artisan 6.0 reported significantly less glare and halo problems. CONCLUSIONS: All currently available phakic IOLs, in particular the ICL and the NuVita lead to a decreased visual performance during night time. Therefore, this phenomenon must be explained to the patient prior to surgery. An increase in the size of the optic should lead to an improvement with reduction of postoperative glare and halos.
