Purpose:
The aim of our retrospecive study is to document our first results with a new toric IOL of the type Basis Z toric of the company 1stQ/Germany regarding corretion of astigmatism, predictability of the target refraction and safety.
Setting:
Augenklinik Bellevue, Lindenallee 21, 24105 Kiel, Germany
Methods:
We implanteted 95 Basis Z toric IOL in patients with cataract and astigmatism. Mean age of the patients was 70 years. The biometry was performed with the Zeiss IOL Master. The Haigis formula was used and the cylinder power of the IOL was calculated with an online calculator programm which is dilivered by 1stQ. The axis was preoperatively marked with the use of the Gerten marker. All operations were performed by one surgeon. A 2.4mm clear cornea inzision was used. For implantation the firstinjektor of 1stQ was used. The follow up ranged fomtbe from four weeks to six months postoperatively. RESULTS All IOL could be implanted within the capsular bag without complications. The IOL showed a good centration. The predictability of the postoperative spherical power was good (planed mean sphere -0.25dpt, 4 weeks -0.19dpt, 6 monts -0.25dpt). The preoperative corneal astigmatism was -2.0dpt and the postoperative astigmatical subjective correction was -0.5dpt. Uncorrected VA was 0.8 and corrected VA 1.0 after 6 months. 4° was the mean deviation of the planed axis of the IOL after 6 months. In three cases the IOL had to be repositioned due to rotation within the learning curve. After using a 5mm rhexis which fully overlapped the optic and using a capsular tension ring no rotaions occured.
Conclusions:
The new toric IOl of the type Basis Z toric is easy to implant and showes a good centration. The predictability concerning the postoperative refractive result is good. Concerning the occurred rotations and long time results further examinations are nessecary.
