Spanish term or phrase: incisión valvulada
I'm translating a text about cataract removal surgery, and in this particular section it is describing the phacoemulsification technique. The technique involves making a microincision to remove the cataract, and this incision is described as "valvulada". I'm struggling to find an appropriate term for this in English, if such a term exists. I've tried googling "valved incision" in English but I don't get any hits, so I don't think that's correct. The full sentence is as follows:

"Como la incisión es valvulada, habitualmente no necesita puntos de sutura para cerrarla, se sella sola."

Any help would be much appreciated.

valved incision


Explanation:
It is a technique used in micro-vitreoretinal surgery that does not require suturing at the end of surgery. It is also called "incisión oblicua/tunelizada".

self-sealing / suturless incision


Explanation:
In phacoemulsification cataract surgery, incisión valvulada (also tunelizada) is a reference to a small suturless self-sealing incision. The most common one is the CCI (clear corneal incision). This and the scleral tunnel incision both use incisión valvulada (tunelizada). Now, as for translation, it depends on context; while as a general reference I would choose either self-sealing or suturless incision, in a more specific context you might want to choose between CCI and scleral tunnel incision depending on your case.

Algunas consideraciones adicionales. Ver aquí, por ejemplo:

"Tras el establecimiento de la facoemulsificación como técnica quirúrgica de elección en la cirugía de la catarata, la incisión corneal valvulada (también llamada tunelizada) unida a la aparición de lentes intraoculares (LIO) plegables (menor tamaño incisional) permitió el cierre sin suturas de la incisión mediante un mecanismo de aposición de los labios de la herida favorecido por la presión intraocular"
http://scielo.isciii.es/scielo.php?script=sci_arttext&pid=S0...

Con un ancho de 3 milímetros, la incisión principal no es tan autosellada como la vía auxiliar. Lo que se hace para que se mantenga autosellada (es decir, no permita la salida o entrada de líquidos cuando no haya un instrumento cruzándola) es que realizamos una incisión valvulada. Esto significa que hay más de un plano de corte, y normalmente se hace cambiando la dirección del cuchillete mientras está dentro del espesor corneal.

A principios de los años 90, la incisión corneal valvulada ganó numerosos adeptos en la cirugía de catarata. La ausencia de sutura reducía el astigmatismo postquirúrgico inducido y aceleraba la recuperación de los ojos operados. Chen, en 1996, trasladó esta técnica a las incisiones esclerales practicadas en vitrectomía describiendo la práctica de esclerotomías tunelizadas con capacidad de autosellado, que no requerían por tanto de sutura al finalizar la vitrectomía 20-gauge. Para ello, una vez realizada la peritomía conjuntival, practicaba, a 6 mm del limbo corneoescleral, una incisión hasta la mitad del espesor escleral, de 2 mm de longitud, que finalizaba a nivel de la pars plana, a 4 mm del limbo. A continuación, levantaba el tapete escleral creado e introducía un bisturí microvitreorretiniano hacia la cavidad vítrea. Este hecho acortó los tiempos quirúrgicos y redujo la irritación conjuntival secundaria a la sutura, que actuaba como cuerpo extraño. Además, gracias a la construcción de las incisiones, al sacar los instrumentos quirúrgicos no se observaban cambios bruscos en la presión intraocular por salida de líquido, de forma que disminuía el riesgo de sangrado intraocular. Por otro lado, también había menos riesgo de herniación de tejido retiniano por las esclerotomías.

Biplanar corneal incision versus multiplanar (e.g. triplanar) corneal incision (and unipolar corneal incision)
https://eyewiki.aao.org/Incision_Construction

To reduce the confusion and facilitate communication regarding these incisions, we believe they should be classified as clear corneal, limbal corneal, or scleral corneal incisions [location] and as single plane, shallow groove, or deeply grooved [arquitecture].
https://ophed.net/system/files/2015/01/Cataract Incisions - ...

This is true for both types of cataract wounds, clear corneal as well as scleral tunnel incisions.
(…)
When we teach architecture to our residents, we all have different preferences ranging from uniplanar to triplanar wound construction.
https://www.eyeworld.org/article-the-first-cut-is-the-deepes...

Location: (…) Incision are now typically created in a temporal location rather than superiorly and in clear cornea or at the anterior limbus (“near clear”) as opposed to traditional scleral tunnel incisions.
Architecture: Architecture refers to the number of incision planes. Biplanar wounds have a larger surface area than uniplanar ones, and may be more stable. The initial partial-thickness groove is made perpendicular to the cornea followed by a beveled entry into the anterior chamber. Triplanar incisions (perpendicular-beveled-perpendicular) consist of an internal corneal lip created by redirecting the keratome tip (“dimple down” maneuver followed by reorienting the keratome parallel to the iris). This functions as a one-way valve and produces a self-sealing, water tight wound when made correctly.

Incisión valvulada” resulta así una referencia inespecífica a una incisión autoestanca (self-sealing). Este tipo de incisiones se consigue por medio de modificaciones en la dirección del corte, creando dos o más planos de corte (perpendicular, oblicuo [“biselado”; beveled] más nuevamente perpendicular si se utilizan tres planos), permitiendo que los labios que se crean cumplan una función de “válvula” que sella la herida sin necesidad -habitualmente- de sutura. Se hace así referencia con “valvulada” a la arquitectura de la incisión, en este caso "con más de un plano de corte". En inglés podría expresarse literalmente como biplanar/multiplanar incision, pero resultará frustrantemente inespecífico (biplanar? Triplanar? Why don't you specify it?) y prono a malinterpretrarse (Do you mean that you perform both type of incisions, biplanar and triplanar?). Así, self-sealing parece una opción tal vez más razonable en este caso; una opción que resulta exactamente igual de inespecífica que el original en referencia en este caso a una incisión con más de un plano de corte.

Valve/valved incision o flap incision sólo lo he encontrado en originales no ingleses. Sobre valve-like incision, lo he visto en algunas traducciones; el único original inglés donde he podido encontrarlo es éste, aunque se trata de información dirigida a pacientes: https://www.nlg.nhs.uk/content/uploads/2013/11/IFP-0005-Cata...

A cataract knife was pushed into the anterior chamber,
parallel to the plane of the iris and about one-eighth inch
from the scleral border. This method produces a valve-like
wound which will not drain
except during depression of the
posterior wound-lip.

Both scleral tunnel and clear corneal incisions, when created properly, possess a self-sealing, valve-like tunnel design whereby maximum architectural stability is obtained in wounds 3.5 mm wide or less and of at least 2.0 mm in length.

neutral  Anne Schulz: I am sure you are right, technically, but with the phrase continuing, "no necesita puntos de sutura para cerrarla, se sella sola", using self-healing or sutureless, el pez se muerde la cola.

  -> Thanks Anne. And you are right you'll need to rephrase (i.e. As a small self-sealing incision is performed sutures are usually not needed). I have not been able to find original-English references with neither valve nor flap in reference to this incision.
