G. Olsen et Rj. Olson, Update on a long-term, prospective study of capsulotomy and retinal detachment rates after cataract surgery, J CAT REF S, 26(7), 2000, pp. 1017-1021
Purpose: To evaluate the retinal detachment risks and neodymium:YAG (Nd:YAG
) capsulotomy rates associated with different cataract approaches and intra
ocular lens (IOL) styles in a long-term, prospective clinical study.
Setting: Clinical practice of 1 ophthalmologist, Felt Collins, Colorado, US
A.
Methods: Prospectively studied were surgical approach, date, and complicati
ons; IOL type; axial length; patient age and sex; Nd:YAG capsulotomy and da
te; and retinal detachment and date.
Results: Phacoemulsification had a lower risk of retinal detachment than in
tracapsular cataract extraction (ICCE) (0.4% versus 5.4%; P < .001) and ext
racapsular cataract extraction (ECCE) (0.4% versus 1.6%; P = .002), Althoug
h retinal detachment was significantly associated with Nd:YAG for ECCE (3.1
% versus 1.0%; P = .01), no patient in the phacoemulsification group had a
retinal detachment after an Nd:YAG treatment. Retinal detachment was strong
ly associated with axial length of 24.0 mm and greater (P < .001), age of 6
0 years or less if axial length was 24.0 mm or greater (for ECCE, P = .001;
for phacoemulsification, P = .01) and sex; that is, male (for ECCE, P = .0
4; for phacoemulsification, P = .02). Regarding IOL styles the Surgidev B20
/20 (P < .001) and AcrySof MA60 (P < .001) had significantly lower Nd:YAG r
ates, while the Cilco UPB 320 GS had a significantly higher Nd:YAG rate (P
< .001).
Conclusion: Cataract surgical approach and IOL style significantly affect N
d:YAG and retinal detachment rates. Being a man, being 60 years or younger,
and especially having an axial length of 24.0 mm or greater were associate
d with detachment. Some Nd:YAG approaches may not put the patient at increa
sed risk for retinal detachment. J Cataract Refract Surg 2000; 26: 1017-102
