Background: In a retrospective data analysis, the influence of lens status on the outcome after primary uncomplicated retinal detachment surgery was evaluated.
Patients and Methods: The analysis is based on data recorded from 364 patients, who underwent surgery due to uncomplicated retinal detachment (265 phakic eyes; 99 pseudophgakic eyes) between 1996 and 1998 by two surgeons.
Results: 178 phakic (group 1; 67%) and 73 pseudophakic patients (group 2; 74%) had completed an inhouse follow up of more than 6 months. As expected, pseudophakic patients were older (p < 0.0001). A definitive primary reattachment was achieved in 149 (83.7%) and 63 cases (86.3%; p=0.6). Pseudophakic eyes presented a greater extension of detachment (4.9 +/- 2.6 vs. 6.3 +/- 2.6 clock hours; p<0.0001), whereas in phakic eyes, a higher number of breaks was detected (1.9 +/- 1.6 vs. 1.1 +/-1.1 breaks; p>0.0001). An primary vitrectomy additionally to the buckle procedure was necessary in 18 and 17% (p=0.8). The groups did not differ regarding development of severe PVR (9.5 vs. 5.8%; p=0.31).
Conclusion: The prognosis of retinal detachment surgery is not dependent on the lens situation if not associated to previous complicated lens surgery. A primary vitrectomy was not more often required in pseudophakic eyes nor was the portion or degree of PVR higher in these cases.
